Abstract :
A serially concatenated system with DUSTM (differential unitary space-time modulation) as an inner code and LDPC (low density parity check codes) as outer code is proposed. And a combined iterative soft decoding algorithm is presented based on serially concatenated structure and turbo principle. This proposed scheme outperforms the trellis coded DUSTM scheme studied previously for the usage of good LDPC codes and the combined iterative decoding algorithm.
