Abstract

This paper presents a blockwise convolutional codes bit-interleaved coded modulation (BC-BICM) scheme for block-fading channels. First, the maximum diversity order is achieved by employing a blockwise maximum distance separable (MDS) convolutional code. Second, the coding gain can be improved by either choosing a better signal labeling scheme for the BICM with iterative decoding or by using better convolutional codes. Simulation results are provided to verify the results.
