Estimating Channels With Hundreds of Sub-Paths for MU-MIMO Uplink: A Structured High-Rank Tensor Approach
Panqi Chen, Lei Cheng
This letter introduces a structured high-rank tensor approach for estimating sub-6G uplink channels in multi-user multiple-input and multiple-output (MU-MIMO) systems. To tackle th…
Striking The Right Balance: Three-Dimensional Ocean Sound Speed Field Reconstruction Using Tensor Neural Networks
Siyuan Li, Lei Cheng, Ting Zhang +2
Accurately reconstructing a three-dimensional ocean sound speed field (3D SSF) is essential for various ocean acoustic applications, but the sparsity and uncertainty of sound speed…
Multipath Time-delay Estimation with Impulsive Noise via Bayesian Compressive Sensing
Xingyu Ji, Lei Cheng, Hangfang Zhao
Multipath time-delay estimation is commonly encountered in radar and sonar signal processing. In some real-life environments, impulse noise is ubiquitous and significantly degrades…
Tensor-based Basis Function Learning for Three-dimensional Sound Speed Fields
Lei Cheng, Xingyu Ji, Hangfang Zhao +2
Basis function learning is the stepping stone towards effective three-dimensional (3D) sound speed field (SSF) inversion for various acoustic signal processing tasks, including oce…
