Optimization Framework and Graph-Based Approach for Relay-Assisted Bidirectional OFDMA Cellular Networks
Yuan Liu, Meixia Tao, Bin Li +1
This paper considers a relay-assisted bidirectional cellular network where the base station (BS) communicates with each mobile station (MS) using OFDMA for both uplink and downlink…
Superimposed XOR: Approaching Capacity Bounds of the Two-Way Relay Channels
Jianquan Liu, Meixia Tao, Youyun Xu +1
In two-way relay channels, bitwise XOR and symbol-level superposition coding are two popular network-coding based relaying schemes. However, neither of them can approach the capaci…
A New SLNR-based Linear Precoding for Downlink Multi-User Multi-Stream MIMO Systems
Peng Cheng, Meixia Tao, Wenjun Zhang
Signal-to-leakage-and-noise ratio (SLNR) is a promising criterion for linear precoder design in multi-user (MU) multiple-input multiple-output (MIMO) systems. It decouples the prec…
Blind Spectrum Sensing by Information Theoretic Criteria for Cognitive Radios
Rui Wang, Meixia Tao
Spectrum sensing is a fundamental and critical issue for opportunistic spectrum access in cognitive radio networks. Among the many spectrum sensing methods, the information theoret…
