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-CDMA系统在频率非选择性Rician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。MC - DS - CDMA is a multi - carrier CDMA system based on the tune - domain spreading, usually, it solves the problems of 1SI（ 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.
