Power Allocation for the Base Matrix of Spatially Coupled Sparse Regression Codes
Nian Guo, Shansuo Liang, Wei Han
We investigate power allocation for the base matrix of a spatially coupled sparse regression code (SC-SPARC) for reliable communications over an additive white Gaussian noise chann…
Orthogonal AMP for Problems with Multiple Measurement Vectors and/or Multiple Transforms
Yiyao Cheng, Lei Liu, Shansuo Liang +2
Approximate message passing (AMP) algorithms break a (high-dimensional) statistical problem into parts then repeatedly solve each part in turn, akin to alternating projections. A d…
Capacity-Achieving Sparse Regression Codes via Vector Approximate Message Passing
Yizhou Xu, YuHao Liu, ShanSuo Liang +4
Sparse regression codes (SPARCs) are a promising coding scheme that can approach the Shannon limit over Additive White Gaussian Noise (AWGN) channels. Previous works have proven th…
Mismatched estimation of non-symmetric rank-one matrices corrupted by structured noise
Teng Fu, YuHao Liu, Jean Barbier +3
We study the performance of a Bayesian statistician who estimates a rank-one signal corrupted by non-symmetric rotationally invariant noise with a generic distribution of singular…
Capacity Optimality of OAMP in Coded Large Unitarily Invariant Systems
Lei Liu, Shansuo Liang, Li Ping
This paper investigates a large unitarily invariant system (LUIS) involving a unitarily invariant sensing matrix, an arbitrary fixed signal distribution, and forward error control…
An Efficient Two-Stage SPARC Decoder for Massive MIMO Unsourced Random Access
Juntao You, Wenjie Wang, Shansuo Liang +2
In this paper, we study a concatenate coding scheme based on sparse regression code (SPARC) and tree code for unsourced random access in massive multiple-input and multiple-output…

Lei Liu, Yiyao Cheng, Shansuo Liang +2
Approximate Message Passing (AMP) is an efficient iterative parameter-estimation technique for certain high-dimensional linear systems with non-Gaussian distributions, such as spar…
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…
Compressed Coding, AMP Based Decoding and Analog Spatial Coupling
Shansuo Liang, Chulong Liang, Junjie Ma +1
This paper considers a compressed-coding scheme that combines compressed sensing with forward error control coding. Approximate message passing (AMP) is used to decode the message.…
