Multicarrier BICM with Adaptive Bit-Loading and Iterative Decoding

In this paper, we describe a combina- tion of OFDM and bit-interleaved coded modulation (BICM) which allows to employ iterative decoding and adaptive modulation on each subchannel. The pro- posed scheme combines the excellent performance of iteratively decoded BICM in fading channels with the advantages of adaptive OFDM in multipath channels, while keeping the decoding complexity low by utilizing one interleaver and one decoder for all subchannels.
