Abstract :
We consider a multiple access relay network where multiple source nodes send independent packets to a common destination with the assistance from a relay node. We assume that the relay node is equipped with multiple antennas and is allowed to choose either spatial multiplexing (SM) or beam forming mode as transmit diversity (TD). We develop an integrated design methodology for MIMO transmission, network coding at the relay node, and channel coding rate at the source nodes that minimizes the end-to-end outage probability.
