Information Theoretic Analysis of Bit-Interleaved Time-Space Codes for Fading Channels

Bit-interleaved coded modulation (BICM) is known to provide a robust solution to the coding prob- lem for wireless channels, as it provides at the same time a large Hamming distance and a large (albeit nonoptimum) Euclidean distance. As BICM splits the code design into the selection of the encoder and the selection of a modula- tion scheme, the design task is simpler than with "standard" space-time codes. In this paper we investigate the performance of BICM over a multiple-antenna channel by evaluating its information-theoretic limits. Further, we provide some design guidelines and we check our results via some simulations.
