Design and performance evaluation of golden interleaving schemes for BICM-ID

Bit-interleaved coded modulation with iterative decoding (BICM-ID) is suitable for the next-generation wireless communication systems. BICM-ID is a bandwidth efficient transmission scheme. And the high performance of BICM-ID depends on the interleaver design. This paper focuses on the design of golden based interleaving schemes in BICM-ID systems. It shows that the golden interleaver and the dithered golden interleaver are not good for BICM-ID when the signal to noise ratio (SNR) is low. While the golden-chaotic interleaver has better performance than the golden and dithered golden interleaver and it also outperforms the random interleaver which is usually used in a BICM-ID system. The effect of the design parameter on the performance of the dithered golden interleaver and the golden-chaotic interleaver is also discussed in the paper. Performance analysis based on the normalized dispersion is provided in the paper and the accuracy of the dispersion analysis is verified by simulation results both in the additive white Gaussian noise (AWGN) channel and Rayleigh fading channels.
