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…
Cooperative Secret Communication with Artificial Noise in Symmetric Interference Channel
Jingge Zhu, Jianhua Mo, Meixia Tao
We consider the symmetric Gaussian interference channel where two users try to enhance their secrecy rates in a cooperative manner. Artificial noise is introduced along with useful…
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…
