Abstract :
Symbol mapping, defined by the signal constellation and the bit labeling is the crucial design parameter to achieve a high coding gain for BICM-ID. In this paper an improved symbol mapping is proposed. The new mapping base on the Transfer Function, a method to calculating the Euclidean Distance. Simulation results show that the new mapping scheme can achieve a better code gain both in AWGN and in Rayleigh fading channels.
