| Summary: | 碩士 === 中華技術學院 === 電子工程研究所碩士班 === 92 === This thesis pertains to the performance analysis of MC-CDMA system over Nakagami fading channels. The channels are apposed to the frequency-selective, slow fading. Three different codes: Hadamard codes, Gold codes and Zadoff-Chu codes are employed for comparison purpose.
The numerical results indicate that the performance of MC-CDMA becomes better as the fading factor increases. Besides, if the number of the carriers gets more, the error probability of the system will decrease. Results also shows, when the fading factor and and the number of carrier is 32, the performances of Walsh Hadamard codes and Zadoff-Chu codes are about the same at low SNR, but the performance of Walsh Hadamard codes is better than others at high SNR.
