Channel Estimation with Tightly-Coupled Antenna Arrays

Bamelak Tadele, Volodymyr Shyianov, Faouzi Bellili, Amine Mezghani

ICASSP 2023accepted

This paper develops a linear minimum mean-square error (LMMSE) channel estimator that takes advantage of the mutual coupling in antenna arrays. We model the mutual coupling through multiport networks and express the singleuser multiple-input multiple-output (MIMO) communication channel in terms of t…

Massive Unsourced Random Access Based on Bilinear Vector Approximate Message Passing

Ramzi Ayachi, Mohamed Akrout, Volodymyr Shyianov, Faouzi Bellili, Amine Mezghani

ICASSP 2022accepted

This paper introduces a new algorithmic solution to the massive unsourced random access (mURA) problem. The proposed uncoupled compressed sensing (UCS)-based scheme relies on slotted transmissions and takes advantage of the inherent coupling provided by the users’ spatial signatures in the form of c…
