Generalized Approximate Message Passing for Massive MIMO mmWave Channel Estimation with Laplacian Prior
Faouzi Bellili, Foad Sohrabi, Wei Yu
This paper tackles the problem of millimeter-Wave (mmWave) channel estimation in massive MIMO communication systems. A new Bayes-optimal channel estimator is derived using recent a…
