Coverage: Partial inventor search
Fourteen representative records inspected across Intel/Mobilian, Qualcomm and individual-assignee metadata. The first-party patent index explicitly binds the Ephi variant on GFSK receiver to Ephraim Zehavi. This is materially broader than the original reported-only entry, but still partial versus the institutional more-than-40 claim. Most pre-2000 Qualcomm patents, Ephi/Ephraim surname variants, continuations and worldwide national phases remain unaudited; no full portfolio count asserted.

Original evidence: reported only
The official profile reports more than forty patents, but no specific record was sufficiently attributed within this bounded search.[19]
Records are counted separately from identified families. Author-reported entries are labelled and may still need publication verification. Inventorship, publication-time applicant and current ownership are different facts. No legal-status, patentability or freedom-to-operate conclusion is made.
Scores prioritize research fit from 1–10; they are not probabilities.
Review: Reviewed with limitations
Proposed capability matches, not confirmed relationships. Scores are analyst judgments with low forecast confidence; researcher interests, capacity and feasibility need confirmation.
10 candidates
Connection 1
Original proposal
Proposal hypothesis: Zehavi can define a coded wireless channel while Gelles specifies an interactive protocol whose correctness survives message corruption.[19][20][57][58]
Proposed first test: Replay a synthetic burst-error channel through an interactive exchange and compare failure probability and latency with uncoded retransmission.
Rank 1/10; fit 9/10 (3 topic overlap + 3 complementarity + 3 feasible first test). Preserved original co-membership proposal in o08. No strictly higher-scoring candidate displaces this original. Interactive coding theory must be instantiated for the chosen channel rather than transferred from an incompatible noise model. No automatic score boost for original membership. Equal scores use existing-first, then stable researcher ID.
Analyst proposal hypothesis, not an established collaboration, commitment, evidence-confidence rating or assessment of researcher quality; confirm participation and access before work.
Connection 2
Original proposal
Proposal hypothesis: Zehavi's coded-modulation practice and Somekh-Baruch's channel-coding theory directly meet on implementation penalties under decoder mismatch.[19][20][87]
Proposed first test: Compare two coded-modulation decoders on a fixed synthetic channel, plotting achieved error rates against the relevant theoretical bound.
Rank 2/10; fit 9/10 (4 topic overlap + 2 complementarity + 3 feasible first test). Preserved original co-membership proposal in o08. No strictly higher-scoring candidate displaces this original. Strong topic overlap but overlapping coding roles reduce complementarity; no measured-channel dataset is presumed. No automatic score boost for original membership. Equal scores use existing-first, then stable researcher ID.
Analyst proposal hypothesis, not an established collaboration, commitment, evidence-confidence rating or assessment of researcher quality; confirm participation and access before work.
Connection 3
Proposal hypothesis: Zehavi's coded modulation and Zaidel's multiuser detection share an uplink reliability problem with coding and interference-analysis roles.[19][20][102]
Proposed first test: Compare coded multiuser reception with orthogonal access in one fixed channel model on error rate and achievable throughput.
Rank 3/10; fit 9/10 (4 topic overlap + 2 complementarity + 3 feasible first test). New pairing outside the frozen portfolio co-member graph. Similar communications expertise makes the roles partly overlapping. Equal scores use existing-first, then stable researcher ID.
Analyst proposal hypothesis, not an established collaboration, commitment, evidence-confidence rating or assessment of researcher quality; confirm participation and access before work.
Connection 4
Proposal hypothesis: Zehavi can define the coded wireless link while Amir Weiss selects compressed sensor messages by estimation value.[19][20][108][109]
Proposed first test: Compare raw and compressed delay-estimation messages under the same coded-link budget on estimation error and latency.
Rank 4/10; fit 9/10 (3 topic overlap + 3 complementarity + 3 feasible first test). New pairing outside the frozen portfolio co-member graph. A good compression ratio is insufficient if it destroys the target statistic. Equal scores use existing-first, then stable researcher ID.
Analyst proposal hypothesis, not an established collaboration, commitment, evidence-confidence rating or assessment of researcher quality; confirm participation and access before work.
Connection 5
Proposal hypothesis: Zehavi's MIMO and coded-link constraints can ground Leshem's distributed wireless resource-allocation policies.[19][20][111][112]
Proposed first test: Simulate a coded MIMO link shared by adaptive users and compare outage and fairness with a fixed resource split.
Rank 5/10; fit 9/10 (3 topic overlap + 3 complementarity + 3 feasible first test). New pairing outside the frozen portfolio co-member graph. A shared channel and workload specification is needed before comparing algorithms. Equal scores use existing-first, then stable researcher ID.
Analyst proposal hypothesis, not an established collaboration, commitment, evidence-confidence rating or assessment of researcher quality; confirm participation and access before work.
Connection 6
Proposal hypothesis: Zehavi's wireless tracking and Noam's interference/estimation methods meet on reliable tracking under spectrum sharing.[19][20][130][131]
Proposed first test: Compare two tracking-and-allocation rules in a synthetic interference channel on location error and outage.
Rank 6/10; fit 9/10 (4 topic overlap + 2 complementarity + 3 feasible first test). New pairing outside the frozen portfolio co-member graph. The first test is analytical/simulation work, not an operational radio trial. Equal scores use existing-first, then stable researcher ID.
Analyst proposal hypothesis, not an established collaboration, commitment, evidence-confidence rating or assessment of researcher quality; confirm participation and access before work.
Connection 7
Original proposal
Proposal hypothesis: Zehavi's wireless link design can supply channel conditions for Medina's fault-tolerant edge-network algorithms.[19][20][100]
Proposed first test: Inject independent link outages and node faults into a small sensor-network simulation and compare recovery delay with static redundancy.
Rank 7/10; fit 8/10 (2 topic overlap + 3 complementarity + 3 feasible first test). Preserved original co-membership proposal in o08. An added candidate, Benjamin M. Zaidel (9/10), ranks above this original because its stated pair-specific roles and first test score higher; this original is limited as follows: Wireless coding and hardware faults need a shared workload; neither source implies a ready integrated implementation. No automatic score boost for original membership. Equal scores use existing-first, then stable researcher ID.
Analyst proposal hypothesis, not an established collaboration, commitment, evidence-confidence rating or assessment of researcher quality; confirm participation and access before work.
Connection 8
Proposal hypothesis: Zehavi's coded-link requirements complement Fish's low-power sensor circuits at the communication duty-cycle boundary.[19][20][89][90]
Proposed first test: Model a fixed sensor stream with two code-rate/duty-cycle settings and compare circuit energy, outage and latency.
Rank 8/10; fit 8/10 (3 topic overlap + 3 complementarity + 2 feasible first test). New pairing outside the frozen portfolio co-member graph. No common fabricated sensor-radio platform is assumed. Equal scores use existing-first, then stable researcher ID.
Analyst proposal hypothesis, not an established collaboration, commitment, evidence-confidence rating or assessment of researcher quality; confirm participation and access before work.
Connection 9
Proposal hypothesis: Teman's low-power memory implementation and Zehavi's coded wireless systems could trade local storage against retransmission energy.[1][19][20]
Proposed first test: Model a sensor buffer under bursty link outages; compare buffer retention energy and retransmission cost for two policies.
Rank 9/10; fit 7/10 (2 topic overlap + 3 complementarity + 2 feasible first test). New pairing outside the frozen portfolio co-member graph. A real radio/circuit energy model is needed before claiming battery-life savings. Equal scores use existing-first, then stable researcher ID.
Analyst proposal hypothesis, not an established collaboration, commitment, evidence-confidence rating or assessment of researcher quality; confirm participation and access before work.
Connection 10
Proposal hypothesis: Zehavi's MIMO processing can provide a regular numerical kernel for Yavits's memory-centric architectures.[19][20][104][105]
Proposed first test: Map a small detector kernel to conventional and memory-centric models and compare bit traffic, latency and decision errors.
Rank 10/10; fit 7/10 (2 topic overlap + 3 complementarity + 2 feasible first test). New pairing outside the frozen portfolio co-member graph. A suitable detector must be selected; genomics acceleration is not proof of MIMO acceleration. Equal scores use existing-first, then stable researcher ID.

Connection 4
Stony Brook University
Original proposal
Goldsmith's current Stony Brook profile documents wireless communication, information theory and signal processing, complementing Zehavi's coding and receiver work; this is a proposed match only.[19][21][103][456]
Simulate a two-user coded link with a declared burst-interference process, fixed power budget and reproducible seeds. Compare an adaptive rate controller with a fixed-rate controller under the same channel realizations; report outage and recovery latency. Measured-trace replay and SDR work are later stages requiring verified trace and hardware access.
Rank 4/10 after semantic revision; analyst score 9 = max(1, 4+3+2): topic overlap 4/4, complementarity 3/3, feasible first test 2/3. Adaptive wireless control closely complements coding expertise, but measured traces and an SDR platform have not been secured; begin with reproducible channel simulation. A bounded offline comparison is specified; required datasets and domain assumptions must still be checked. Original retained exactly at rank 4; preceding alternatives are Robert Calderbank (10; 4+3+3), Elza Erkip (10; 4+3+3), Muriel Medard (10; 4+3+3). Its first stage now has explicit unconfirmed platform, protocol or interface prerequisites; higher totals reflect the other scoped tests, not comparative researcher quality.
Proposed fit, not an assertion of a new or active relationship. Independent review pending; forecast confidence low. Partner interest, capacity, data access and any required experimental approvals/resources are unverified. Post-review scope: Adaptive wireless control closely complements coding expertise, but measured traces and an SDR platform have not been secured; begin with reproducible channel simulation. This revised proposal awaits independent targeted re-review; simulated outcomes would establish model behavior only, not biological, clinical or deployed benefit.
