| 摘 要： | MC—DS—CDMA系统是基于时域扩展的多载波CDMA系统，它通常使用少量的子载波来解决ISI和ICI问题。对同步MC—DS—CDNA系统在频率非选择性Riciall衰落信道中的抗噪声性能进行了分析。仿真结果表明，非选择性Rician衰落参数D对系统的误比特率影响很大，在信噪比相同时，误比特率随D增加而增大。

| Abstract: | MC-DS-CDMA is a multi-carrier CDMA system based on the time-domain spreading.Usually,it solves the problems of ISI(inter-symbol-interference)and ICI(inter-chip-interference)by using less sub-carriers.The anti-noise performance of the synchronous MC-DS-CDMA system in a frequency non-selective Rician fading channel is analyzed in this paper.The simulation results indicate that the non-selective Rician fading parameter D has a large influence on the bit error rate, and BER rises as the parameter D increases. |

| Keywords: | multi-carrier CDMA rician fading bit error rate |
