Abstract
In this thesis, we investigate bit-interleaved coded di erential amplitude/ phase (APM) schemes for correlated fading channels. For uncoded APM schemes, the design criteria and optimization procedures for table construction and bit labeling search are investigated. For convolutional-coded APM schemes, the design criteria, which aim at improving the performance of error oor region, are proposed for the use of two kinds of interleavers, respectively. On the other hand, low-density parity-check (LDPC)-coded APM schemes are then designed by applying EXIT (extrinsic information transfer )-chart-based code search algorithms. The water-fall region performance of the LDPC-coded scheme can be improved, when comparing to that of the convolutional-coded schemes.
