Abstract :
The goal of the future terrestrial and mobile digital video broadcasting standards is to combine diversity and spatial multiplexing in order to fully exploit the multiple-input multiple-output (MIMO) channel capacity. Full-rate full-diversity (FR-FD) space-time codes (STC) such as the Golden code, that maximize the rate preserving the diversity gain, are studied for that purpose. Most of them present a high-complexity detection problem which results in a handicap for their hardware implementation. Therefore, we analyze the performance of a sub-optimal full-rate full-diversity 2×2 STC, whose design reduces the complexity of the detection, as an alternative for future MIMO broadcasting TV systems. The assessment of the proposed STC code is carried out over the bit-interleaved coded modulation (BICM) scheme of DVB-T2 system which includes low-density parity check (LDPC) codes for error correction. Finally, soft STC list detection is studied in order to generate soft information for LDPC decoding.
