Efficient and Robust Compressed Sensing using High-Quality Expander Graphs
Sina Jafarpour, Weiyu Xu, Babak Hassibi +1
Expander graphs have been recently proposed to construct efficient compressed sensing algorithms. In particular, it has been shown that any -dimensional vector that is -spars…

A Local Tree Structure is NOT Sufficient for the Local Optimality of Message-Passing Decoding in Low Density Parity Check Codes
Weiyu Xu
We address the problem,`Is a local tree structure sufficient for the local optimality of message passing algorithm in low density parity check codes?'.It is shown that the answer i…
