Description/Abstract

It is widely recognised that the choice of a speci?c bit-to-symbol mapping scheme or a bene?cial constellation labelling is an in?uential factor, when designing bit-inter-leaved coded modulation using iterative decoding (BICM-ID) for the sake of achieving a high iteration gain. Generally, a larger constellation size of a higher-dimensional space renders the bit-to-symbol mapping design more ?exible. In this paper, we ?rst de?ne a ?exibility measure based on the extrinsic information transfer (EXIT) characteristics of bit-to-symbol mapping schemes. Secondly, we investigate the effect of expanding the constellation to a higher-dimensional space on our proposed EXIT characteristic ?exibility index, when transmitting diverse numbers of bits per joint symbol.
