摘要
研究了多载波直扩 CDMA系统在相关 Rayleigh衰落信道中的系统性能 .纠正并补充了在相关衰落信道下分集系统的误码率公式 .通过系统仿真和对理论公式的数值计算 ,在指数时延谱的信道环境下比较了 MC- DS- CDMA系统和采用 Rake接收机的单载波系统的性能 .
The performance of a multicarrier DS CDMA system is studied in the correlated fading channel. The formula of the diversity system BER is revised, and through system simulation and numerical calculation, a comparison is made between the performance of MC-DS-CDMA system and that of the single-carrier Rake system in the channel with an exponential power delay profile.
