摘要：

The mapping from binary sequences to space-time matrices is an important issue in designing space-time coded multiple-antenna systems where different mapping schemes may lead to different bit-error-rate (BER) performance. In this letter, we use a binary switching algorithm to investigate the mappings of bit-interleaved coded modulation with iterative demodulation/decoding (BICM-ID) for space-time modulation. Both coherent and noncoherent space-time modulation in the cases of no a priori information and perfect a priori information of the coded bits for the demodulator are considered.
