Low Complexity Detector for XL-MIMO Uplink: A Cross Splitting Based Information Geometry Approach
Wenjun Zhang, An-An Lu, Xiqi Gao
In this paper, we propose the cross splitting based information geometry approach (CS-IGA), a novel and low complexity iterative detector for uplink signal recovery in extralarge-s…
Precoder Design for User-Centric Network Massive MIMO: A Symplectic Optimization Approach
Pengxu Lin, An-An Lu, Xiqi Gao
In this paper, we utilize symplectic optimization to design a precoder for user-centric network (UCN) massive multiple-input multiple-output (MIMO) systems, where a subset of base…
Symplectic Optimization for Cross Subcarrier Precoder Design with Channel Smoothing in Massive MIMO-OFDM System
Yuxuan Zhang, An-An Lu, Xiqi Gao
In this paper, we propose a cross subcarrier precoder design (CSPD) for massive multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems. The…
Precoder Design for User-Centric Network Massive MIMO with Matrix Manifold Optimization
Rui Sun, Li You, An-An Lu +3
In this paper, we investigate the precoder design for user-centric network (UCN) massive multiple-input multiple-output (mMIMO) downlink with matrix manifold optimization. In UCN m…
