The research for optimal mapping strategies for concatenation scheme (MLC-STBC) in Rayleigh fading channels

In this paper according to the analysis of the characteristics of multilevel codes (MLC) and space-time block codes (STBC), a concatenation scheme combining MLC and STBC is proposed over Rayleigh fading channels. According to the fact that the MLC system can achieve optimal performance by the BP (block partitioning) rule, the optimal set partitioning of the MLC-STBC system is investigated in this paper. After the analysis and computer simulations, it is proved that the MLC-STBC system has the same optimal set partitioning as the MLC system.
