This paper investigates the error performance and precoder design for a bandwidth-efficient bit-interleaved coded modulation (BICM) system over a non-orthogonal amplify-and-forward (NAF)half-duplex single-relay channel. A tight union bound on the bit error probability (BEP) is first derived for an arbitrary block length of $2N$ using a $2N\times 2N$ precoder. This bound provides an useful tool to predict the error performance. Attention is then devoted to the system using $2\times 2$ precoder… CONTINUE READING
