In order to increase the bandwidth efficiency and receiver robustness the wireless communication standards such as DVB-T2 or DVB-NGH are used. In order to fully exploit the Multiple-Input Multiple-Output (MIMO) channel capacity, the diversity and spatial multiplexing are combined. However, to achieve large capacity of Full-Rate Full Diversity (FRFD) space-time codes, most of them present high complexity for soft detection. For that a low complexity soft detection algorithm is proposed for the reception of FRFD space-frequency block codes in BICM (Bit Interleaved Coded Modulation) Orthogonal Frequency Division Multiplexing (OFDM) systems.
