Online Wideband MIMO Channel Reconstruction from Periodically Swept RBs via Incremental CP Updates
Boxin Huang, Libin Zheng, Minru Bai +1
Periodic resource-block (RB) scanning leaves most of the current wideband channel unobserved and mixes measurements of different ages. We develop an online canonical polyadic track…
An accelerated semi-proximal ADMM with applications to multi-block sparse optimization problems
Peng Liu, Liang Chen, Minru Bai
As an extension of the alternating direction method of multipliers (ADMM), the semi-proximal ADMM (sPADMM) has been widely used in various fields due to its flexibility and robustn…
Group Sparse-based Tensor CP Decomposition: Model, Algorithms, and Applications in Chemometrics
Zihao Wang, Minru Bai, Liang Chen +1
The CANDECOMP/PARAFAC (or Canonical polyadic, CP) decomposition of tensors has numerous applications in various fields, such as chemometrics, signal processing, machine learning, e…
ZF Beamforming Tensor Compression for Massive MIMO Fronthaul
Libin Zheng, Zihao Wang, Minru Bai +1
In the rapidly evolving landscape of 5G and beyond 5G (B5G) mobile cellular communications, efficient data compression and reconstruction strategies become paramount, especially in…
