Bayesian matching pursuit: A finite-alphabet sparse signal recovery algorithm for quantized compressive sensing
In this letter, we consider the problem of detecting finite-alphabet sparse signals from noisy
and coarsely quantized measurements. To solve this problem, we propose a greedy sparse …

Greedy algorithms for sparse and positive signal recovery based on bit-wise MAP detection
We propose a novel greedy algorithm to recover a sparse signal from a small number of
noisy measurements. In the proposed method, a new support index is identified for each …
