On the equivalence of blind equalizers based on MRE and subspace intersections
TL;DR: Although these methods seem, at first sight, unrelated, it is shown that certain variants of the SSI and the MRE methods both optimize a new blind criterion, which is referred to as maximum coherence and, thus, are equivalent.
Opportunistic interference alignment for MIMO IMAC: Effect of user scaling over degrees-of-freedom

TL;DR: The antenna selection-based OIA does not fundamentally change the user scaling required to achieve KS DoF if L is fixed, compared with the single-input multiple-output (SIMO) IMAC case, and it is shown that the SVD- based OIA can greatly reduce the required user scaling to SNR(K-1) S-L+1 through optimizing weight vectors at each MS.

An interference suppression scheme with joint channel-data estimation
TL;DR: An adaptive space-time receiver with joint channel-data estimation (JCDE) to combat time-varying (TV) multipath channels in the presence of undesired cochannel interference (CCI).

TL;DR: It is demonstrated that the quad-sector architecture has a higher capacity for 90% area coverage than the tri-sector cell and the combination of interleaved channel assignment (ICA) andInterleaved polarization assignment (IPA) offered the most enhanced capacity.

Cache-Assisted Broadcast-Relay Wireless Networks: A Delivery-Time Cache-Memory Tradeoff
TL;DR: In this article, the authors study the fundamental limits of a cache-aided broadcast-relay wireless network consisting of one central base station, $M$ cache-equipped transceivers and $K$ receivers from a latency-centric perspective.
