Transmit Signal and Bandwidth Optimization in Multiple-Antenna Relay Channels
Chris T. K. Ng, G.J. Foschini · IEEE Transactions on Communications · 2011
In a multiple-antenna relay channel, the full-duplex cut-set capacity upper bound and decode-and-forward rate are formulated as convex optimization problems. For half-duplex relaying, bandwidth allocation and transmit signals are optimized jointly. Moreover, achievable rates based on the compress-and-forward strategy are presented using rate-distortion and Wyner-Ziv compression schemes.
