Comparative Study for Bit-Interleaved Coded Modulation with Iterative Decoding
We consider iteratively decoded bit-interleaved coded modulation (BICM-ID) for bandwidth-efficient transmission over AWGN channel, where the bit error rate is reduced through iterations between a demapper and a channel decoder. In this paper, we conduct a comparative study, using intensive set of simulations, to examine the different parameters which affect the performance of BICM-ID in term of convergence and BER error floor. More specifically the following parameters are considered: the effect of convolutional code constraint, interleaver size and mapping schemes. In this comparative study, these mapping schemes were used: set partitioning (SP), modified set partitioning (MSP), Schreckenbach, M16 and maximum squared Euclidean weight (MSEW).
