| Summary: | 碩士 === 國立暨南國際大學 === 電機工程學系 === 93 === The thesis studies the determination of optimum switching levels under forward error correction (FEC) codes. For slow fading channels, we adopt damping effect to improve system’s efficiency. For fast fading channels, the performance can be improved by offsetting the switching levels. Besides the theoretical study, a software 802.16 transceiver in Matlab is developed. This software transceiver can efficiently speed up the study of adaptive modulation.
