Abstract :
Diversity-multiplexing tradeoff (DMT) of asymmetric two-user full-duplex cooperative multiple-access (CMA) channels with multiple-antenna terminals is studied. The channel is asymmetric in the sense that the users are not restricted to have the same multiplexing and diversity gains. Using the network capacity cut-set bound, we first derive the DMT upper bounds of a general K-user CMA channel. Following that, we focus on the two-user case and show that the upper bound can be achieved using Wyner-Ziv-type compress-and-forward (CF) based cooperation given that the transmission resources are properly allocated for transmitting the cooperation information and the user information. A transmission scheme is then proposed and proved to be DMT optimal both theoretically and numerically.
