| Summary: | 博士 === 國立清華大學 === 電機工程研究所 === 84 === Three important techniques: adaptive equalization, coded
modulation, and unequal error protection (UEP), are considered
in this study for improving the quality of various
communication systems. One objective of this research is
to analyze the performance of adaptive maximum-likelihood
sequence estimation (MLSE) for uncoded and trellis-coded
modulation (TCM) systems over multipath fading channels
under the consideration of imperfect channel estimates. The
other objective is to construct good UEP codes. Three coding
schemes, which cover the historical development of coding
theory, are considered for UEP: block codes, convolutional
codes, and coded modulation.
