Last-generation and future wireless communication technologies, such as DVB-T2 or DVB-NGH, offer multi antenna transmission and reception to improve bandwidth efficiency and receiver robustness. To effectively maximise the capacity of multiple-input multiple output (MIMO) channels, the major goal is to combine diversity and spatial multiplexing. Full-rate full-diversity (FRFD) space-time codes (STC) like the Golden code are being researched for this purpose. Despite their larger attainable capacity, most of them have a high soft detection complexity, preventing them from being used in bit-interleaved coded modulation (BICM) schemes with soft-input decoders. This research analyses the performance of LDPC and Turbo codes with a low complexity soft detection technique for receiving FRFD space-frequency block codes in BICM orthogonal frequency division multiplexing (OFDM) systems. The suggested detector has a minimal and fixed complexity, which avoids the list sphere decoder's (LSD) changeable nature, which is reliant on noise and channel circumstances. According to complexity and simulation-based performance results, the suggested detector performs near to the ideal log-maximum a posteriori (MAP) detection in a range of DVB-T2 broadcasting circumstances.
