Vector Approximate Message Passing With Arbitrary I.I.D. Noise Priors
Mohamed Akrout, Tiancheng Gao, Faouzi Bellili +1
Approximate message passing (AMP) algorithms are devised under the Gaussianity assumption of the measurement noise vector. In this work, we relax this assumption within the vector…
