On Capacity Optimality of OAMP: Beyond IID Sensing Matrices and Gaussian Signaling
Lei Liu, Shansuo Liang, Li Ping
This paper investigates a large unitarily invariant system (LUIS) involving a unitarily invariant sensing matrix, an arbitrarily fixed signal distribution, and forward error contro…
Memory Approximate Message Passing
Lei Liu, Shunqi Huang, Brian M. Kurkoski
Approximate message passing (AMP) is a low-cost iterative parameter-estimation technique for certain high-dimensional linear systems with non-Gaussian distributions. However, AMP o…
Irregularly Clipped Sparse Regression Codes
Wencong Li, Lei Liu, Brian M. Kurkoski
Recently, it was found that clipping can significantly improve the section error rate (SER) performance of sparse regression (SR) codes if an optimal clipping threshold is chosen.…
Capacity Optimality of AMP in Coded Systems
Lei Liu, Chulong Liang, Junjie Ma +1
This paper studies a large random matrix system (LRMS) model involving an arbitrary signal distribution and forward error control (FEC) coding. We establish an area property based…
