碩士 === 國立交通大學 === 電信工程系 === 90 === In this thesis, the concept of channel similarity is explored by two different methodologies---an analytical methodology based on divergence, and an empirical methodology based on error free run matching. In the analytical methodology, we showed that divergences can serve as an index to channel similarity. We then proceeded to compare the resemblance between the Gilbert-Elliott and Polya channels, and obtained that for some very specific case, the two channels are not similar to each other. In the empirical methodology, we examined which of the two channel models, Gilbert-Elliott and Polya, is more suitable to approximate the binary-quantized simplification of a continuous multipath Rayleigh fading channel. In terms of the EFR quantitative index, we showed that the Gilbert-Elliott channel is a better approximation to the binary-quantized multipath Rayleigh fading channel than the Polya model. A side result is that among all Rayleigh fading channels examined, the Gilbert-Elliott channel is particularly suitable to represent a two-path Rayleigh fading channel.
