A BICM-ID based FM IBOC DAB system

In this paper, the application bit-interleaved coded modulation with iterative decoding (BICM-ID) for FM IBOC DAB systems over Rayleigh fading channel is addressed. As compared with TCM which utilizes symbol interleaved, in addition to implementation advantages, BICM-ID performs well on fading channel for bandwidth-efficient transmission. Here, this dissertation analyzes the key element of BICM-ID, and then addresses the optimal solution to yield a significant improvement for FM IBOC DAB systems. Various analytical and simulation results reveal that our design optimized with BICM-ID outperform the conventional approach in civilian applications.
