Application of turbo equalizer for multimode block-coded modulation

Abstract (in Japanese) (See Japanese page) 
(in English) A coded modulation can improve the performances of both frequency efficiency and error correction in wireless communications. Also, an adaptive modulation in which the modulation and coding change adaptively according to the transmission channels is widely used. A multimode block-coded modulation (BCM) enables the adaptive transmission in one code having multiple modulations or rates, and keeps the coded modulation property. In this paper, we propose the log-likelihood-ratio (LLR) based decoding of this multimode BCM. Since the multimode code includes different modes in one code, LLR is divided into that of determining the mode and that of determining bits. Then, the multimode decoding using LLR is enabled. Furthermore, we propose a turbo-equalizing scheme for the multimode BCM using these LLRs. Some numerical results show the compatibility of the proposed scheme.
