Abstract:

We investigate the effect of the different labeling map on the LDPC-BICM-ID system performance based on the extrinsic information transfer(EXIT)chart and computer simulation. The results show that Gray mapping is the best compared with the other optimized labeling strategies designed especially for the convolutional codes coded BICM-ID systems.

Key words: low-density parity-check(LDPC)code, bit-interleaved coded modulation with iterative decoding(BICM-ID), labeling map, extrinsic information transfer chart
