| Abstract: | This paper considers bit-leaved coded modulation (BICM) for bandwidth-efficient transmission over AWGN channels. A simple iterative decoding (ID) method with hard-decision feedback is suggested to achieve better performance. The paper shows that convolutional codes with good Hamming-distance property can provide large free Euclidean distance for BICM-ID. BICM-ID allows an efficient combination of punctured convolutional codes and multiphase/level modulation, and therefore provides a simple mechanism for variable-rate transmission. |
