Information-Theoretic Limits for Rectangular Spiked Matrix Models with Rotationally Invariant Noise
Qun Chen, Rudy Skerk, Jean Barbier +3
We study the information-theoretic limits of inference in rectangular rank-one spiked matrix models with additive rotationally invariant noise, thereby going beyond the standard as…
K-step Vector Approximate Survey Propagation
Qun Chen, Haochuan Zhang, Huimin Zhu
Approximate Message Passing (AMP), originally developed to address high-dimensional linear inverse problems, has found widespread applications in signal processing and statistical…
Vector Approximate Survey Propagation

Approximate Message Passing (AMP), originally designed to solve high-dimensional linear inverse problems, has found broad applications in signal processing and statistical inferenc…
Symbol Detection for Coarsely Quantized OTFS
Junwei He, Haochuan Zhang, Chao Dong +1
This paper explicitly models a coarse and noisy quantization in a communication system empowered by orthogonal time frequency space (OTFS) for cost and power efficiency. We first p…
Expectation-Maximization-Aided Hybrid Generalized Expectation Consistent for Sparse Signal Reconstruction
Qiuyun Zou, Haochuan Zhang, Hongwen Yang
The reconstruction of sparse signal is an active area of research. Different from a typical i.i.d. assumption, this paper considers a non-independent prior of group structure. For…
Estimation for High-Dimensional Multi-Layer Generalized Linear Model -- Part II: The ML-GAMP Estimator
Qiuyun Zou, Haochuan Zhang, Hongwen Yang
This is Part II of a two-part work on the estimation for a multi-layer generalized linear model (ML-GLM) in large system limits. In Part I, we had analyzed the asymptotic performan…
Estimation for High-Dimensional Multi-Layer Generalized Linear Model -- Part I: The Exact MMSE Estimator
Haochuan Zhang, Qiuyun Zou, Hongwen Yang
This two-part work considers the minimum means square error (MMSE) estimation problem for a high dimensional multi-layer generalized linear model (ML-GLM), which resembles a feed-f…
Multi-Layer Bilinear Generalized Approximate Message Passing
Qiuyun Zou, Haochuan Zhang, Hongwen Yang
In this paper, we extend the bilinear generalized approximate message passing (BiG-AMP) approach, originally proposed for high-dimensional generalized bilinear regression, to the m…
Symbol Detection for Massive MIMO AF Relays Using Approximate Bayesian Inference
Haochuan Zhang, Qiuyun Zou
For massive MIMO AF relays, symbol detection becomes a practical issue when the number of antennas is not large enough, since linear methods are non-optimal and optimal methods are…
