Abstract :
This paper proposes a new efficient stopping criterion for bit-interleaved coded modulation with iterative decoding (BICM-ID) system. The new criterion modifies the existing widely used hard-decision-aided (HDA) stopping criterion by adopting the simple scheme and the idea of setting the second maximum iteration numbers (Imax) in accordance with different signal-to-noise ratios (SNRs). We name it S-Imax-HDA stopping criterion. Simulations comparing with the fixed scheme and the original HDA stopping criterion show that the new criterion can not only greatly reduce the iteration numbers but also can achieve excellent performance in terms of bit error rate (BER). When BER is at 10-5, the new proposed S-Imax-HDA stopping criterion can get about 0.2dB coding gains compared with the fixed scheme and 0.3dB coding gains compared with the original HDA stopping criterion.
