Mutual-Information-Based Adaptive Bit-Loading Algorithms for LDPC-Coded OFDM

In this paper we analyze the performance of an LDPC-coded OFDM system with adaptive bit-loading based on mutual information. We demonstrate that the mutual information between the transmitted binary sequence and the soft information input to LDPC decoder well characterizes the performance of the LDP...
