Joint Space-Time Coded Modulation and channel coding for iterative non-coherent MIMO schemes

A new joint channel-coding, modulation and space-time coding scheme is proposed as a new multi-antenna Multi-Input Multi-Output (MIMO) scheme called “Matrix Coded Modulation” or “MCM”. The existing non-coherent schemes such as the Differential Space-Time Modulation (DSTM) leads to performance degradation compared to coherent systems in which perfect channel state information (CSI) is assumed. Decoding in the MCM schemes is performed iteratively, based on specified detection criteria. This new scheme is also adapted for coherent and non-coherent systems. The polynomial distribution of the Euclidean distance based on the detection criteria depends on the Hamming minimal distance of the channel-error correcting code employed in the MCM scheme.
