Abstract

We propose the combination of iterative demodulation and iterative source-channel decoding as a multiple Turbo process. The receiver structures of bit-interleaved coded modulation with iterative decoding (BICM-ID), iterative sourcechannel decoding (ISCD), and iterative source coded modulation (ISCM) are merged to one novel Turbo system, in which in two iterative loops reliability information is exchanged between the three single components, demodulator, channel decoder, and (softbit) source decoder. Simulations show quality improvements compared to the different previously known systems, which use iterative processing only for two components of the receiver.
