| Summary: | 碩士 === 中華技術學院 === 電子工程研究所碩士班 === 97 === In this thesis, performance analysis of coherent reception of direct sequence–code division multiple access(DS-CDMA) over Weibull fading channel is investigated. The fading channel model is assumed to be a frequency-selective slowly fading with paths being independent Weibull fading. At the receiver, the rake receiver is employed.
Results shows that when the shape parameter increases the performance of a DSSS CDMA system over Weibull fading channel can be improved. Besides, the performance has been shown to be proportional to the number of fingers but reversely proportional to the number of users.
