Matrix-Monotonic Optimization for MIMO Systems
Chengwen Xing, Shaodan Ma, Yiqing Zhou
For MIMO systems, due to the deployment of multiple antennas at both the transmitter and the receiver, the design variables e.g., precoders, equalizers, training sequences, etc. ar…
Adaptive Multi-objective Optimization for Energy Efficient Interference Coordination in Multi-Cell Networks
Zesong Fei, Chengwen Xing, Na Li +1
In this paper, we investigate the distributed power allocation for multi-cell OFDMA networks taking both energy efficiency and inter-cell interference (ICI) mitigation into account…
Design of Binary Network Codes for Multi-user Multi-way Relay Networks
Ang Yang, Zesong Fei, Chengwen Xing +3
We study multi-user multi-way relay networks where user nodes exchange their information through a single relay node. We use network coding in the relay to increase the through…
How to Understand LMMSE Transceiver Design for MIMO Systems From Quadratic Matrix Programming
Chengwen Xing, Shuo Li, Zesong Fei +1
In this paper, a unified linear minimum mean-square-error (LMMSE) transceiver design framework is investigated, which is suitable for a wide range of wireless systems. The unified…
A Matrix-Field Weighted Mean-Square-Error Model for MIMO Transceiver Designs
Chengwen Xing, Wenzhi Li, Shaodan Ma +2
In this letter, we investigate an important and famous issue, namely weighted mean-square-error (MSE) minimization transceiver designs. In our work, for transceiver designs a novel…
