摘　　要：该文主要讨论多载波CDMA蜂窝系统在下行信道中的同信道干扰问题,理论分析了同信道干扰的解析表达式,并通过计算机仿真得出了在一定的传播损耗下多载波CDMA蜂窝系统下行信道的性能。通过仿真发现,即使在有小区间同信道干扰情况下,通过简单的小区布置,多载波CDMA蜂窝系统下行信道就可以有很大的信道容量。In this paper, the co-channel interference on the downlink channel of the MC-CDMA cellular system is investigated. The analytic formula of the co-channel interference is induced. The downlink channel performance of the MC-CDMA cellular system with co-channel interference is obtained by the Monte Carlo simulations. The simulations show that the MC-CDMA cellular system has large capacity under co-channel interference when the frequency reuse factor is 1/7.
