Finite-SNR Diversity-Multiplexing Tradeoff for Two-Way Multi-Antenna Relay Fading Channels
In this paper, we study the diversity-multiplexing tradeoff (DMT) of two-way relay channels (TWRC) with multiantenna relay at finite signal-to-noise ratio (SNR). A two-phase decode...

Stability and Performance Issues of a Relay Assisted Multiple Access Scheme
In this paper, we examine the operation of a node relaying packets from a number of users to a destination node. We assume that the relay does not have packets of its own, the traf...
