Robust Linear Precoder Design for Multi-cell Downlink Transmission
Ali Tajer, Narayan Prasad, Xiaodong Wang
Coordinated information processing by the base stations of multi-cell wireless networks enhances the overall quality of communication in the network. Such coordinations for optimiz…
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…
(n,K)-user Interference Channels: Degrees of Freedom
Ali Tajer, Xiaodong Wang
We analyze the gains of opportunistic communication in multiuser interference channels. Consider a fully connected -user Gaussian interference channel. At each time instance onl…
Multiuser Diversity Gain in Cognitive Networks
Ali Tajer, Xiaodong Wang
Dynamic allocation of resources to the \emph{best} link in large multiuser networks offers considerable improvement in spectral efficiency. This gain, often referred to as \emph{mu…
