Abstract
A new iterative decoding (ID) scheme is suggested for bit-interleaved coded modulation (BICM). The bit-metric generation at the demodulator is optimised with the soft-output feedback from the convolutional deco der. Computer simulation results indicate that BICM-ID, with a few ite rations, significantly outperforms conventional trellis coded modulati on and is therefore another promising technique to achieve large codin g gain without bandwidth expansion.
