Abstract :
We study the dynamic decode and forward (DDF) protocol for a single half-duplex relay, single-antenna channel with quasi-static fading. We analyze the diversity-multiplexing tradeoff (DMT) of the DDF protocol for the case of finite block-lengths, and provide simple constructions of explicit, DMT optimal codes. Reduced complexity lattice decoding algorithms for the proposed codes are investigated.
