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…
Quadratic Message Passing for Generalized Quadratic Equations Model
Huimin Zhu
For approximate inference in the generalized quadratic equations model, many state-of-the-art algorithms lack any prior knowledge of the target signal structure, exhibits slow conv…

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…
