In many communications systems, data can be divided into different importance levels. For these systems, unequal error protection (UEP) techniques are used to guarantee lower BER for the more important classes. In particular, if the precise characteristics of the channel are not known, UEP can be used to recover the more important classes even in poor receiving conditions. In this paper, we derive...
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...
