We propose a pragmatic labeling design based on the extrinsic information transfer (EXIT) chart for bit-interleaved coded modulation with iterative decoding on multiple-input-multiple-output channels. In our design, the EXIT chart is used to determine a candidate set of labelings which have representative demapper transfer curves. Then, a procedure to generate these labelings is provided based on...
In this paper, labeling is jointly designed with the outer code by the EXIT chart based analysis to improve the performance of bit-interleaved coded modulation with iterative decoding. A systematic design methodology is proposed for regular modulation schemes which can easily obtain a set of labelings with various slopes. Given an outer code, the optimal labeling which has the steepest slope but still...
This paper addresses an iterative receiver with joint detection and decoding for multi-carrier code division multiple access (MC-CDMA) systems employing multi-sequence signaling. A bit-interleaved coded modulation (BICM) technique, facilitating the "turbo principle" receiver through iterative processing, is utilized to maximize the frequency diversity, followed by a multi-sequence signaling...
