Design and Analysis of Labeling Map Methods for BI-STCM-ID System

Bit-Interleaved Space-Time Coded Modulation with Iterative Decoding(BI-STCM-ID) has been considered as an attractive approach due to its significant performance improvement and high data rate,whereas relatively low decoding complexity.The labeling maps are studied as one of the crucial design parameters to achieve a high coding gain over the iterations.A defined region optimum symbol mapper(DRO) and adaptive labeling method are proposed in this paper.By(analysis) of Error Free Bound(EF Bound) and Character parameters of various labeling maps,key parameters are illustrated,which determine BER performance of BICM-ID and BI-STCM-ID.Design rules on the labeling maps are also presented in this paper.
