Abstract :
We develop an optimization technique for a two way asynchronous relay network. A space-time processing based transceiver is proposed for spatial multiplexing in a two-way relay network. The optimization aims to minimize the transmission power at the relays while satisfying the signal to interference-plus-noise ratio (SINR) target for each user. The problem is solved using semidefinite programming.
