Description
Summary:碩士 === 中原大學 === 電機工程研究所 === 91 === In this thesis, the performance of turbo code is investigated in the slow frequency hopping spread spectrum multiple access (FH/SSMA) system with thermal noise and Rayleigh fading. When perfect side information is unavailable to the receiver, we propose four methods to estimate the variance of the signal and four methods to estimate the mean of the signal. Based on simulation results, we conclude that there is little difference between the performance with perfect side information and that without.
