Diffusion-Based Noise-Adaptive Null-Space Channel Estimation for OFDM Systems
Heqiang Qi, Yirun Chen, Xiangming Meng +3
Accurate channel estimation in orthogonal frequency division multiplexing (OFDM) systems remains challenging when demodulation reference signal (DMRS) observations are sparse and n…
Approximate Message Passing with Nearest Neighbor Sparsity Pattern Learning
Xiangming Meng, Sheng Wu, Linling Kuang +3
We consider the problem of recovering clustered sparse signals with no prior knowledge of the sparsity pattern. Beyond simple sparsity, signals of interest often exhibits an underl…
Message-Passing Receiver for Joint Channel Estimation and Decoding in 3D Massive MIMO-OFDM Systems
Sheng Wu, Linling Kuang, Zuyao Ni +4
In this paper, we address the message-passing receiver design for the 3D massive MIMO-OFDM systems. With the aid of the central limit argument and Taylor-series approximation, a co…
Concise Derivation of Complex Bayesian Approximate Message Passing via Expectation Propagation
Xiangming Meng, Sheng Wu, Linling Kuang +1
In this paper, we address the problem of recovering complex-valued signals from a set of complex-valued linear measurements. Approximate message passing (AMP) is one state-of-the-a…
