摘要

本文研究采用ＢＰＳＫ调制、相干ＰＡＫＥ接收的随机访问多码ＣＤＭＡ（ＲＡＭＣＣＤＭＡ）在频率选择性Ｎａｋａｇａｍｉ多径衰落、噪声信道（ＭＦＮＣ）中的容量性能．建立系统模型后，推导出了多用户条件下接收机输出的条件概率分布及判决平均比特误码率，并以Ｒａｙｌｅｉｇｈ（Ｎａｋａｇａｍｉ的特例）多径衰落、噪声信道为例，计算了系统容量的数值解．分析表明：ＲＡＭＣＣＤＭＡ解决了普通ＤＳＣＤＭＡ系统存在的用户可传信息速率受限（过低）的问题，能在不增加射频带宽的前题下为用户提供高峰值速率信息传送，而且保证了容量没有明显下降．文中还对理论分析的关键结果进行了仿真

Abstract

In this paper

we study capacity performance of Random Access Multi Code CDMA （RAMC CDMA） in Nakagami frequency selective multipath fading and nosy channels （MFNC）.The transmitters adopt BPSK modulation and the coherent RAKE receivers are assumed.Having built the system model

we analyze conditional probability distribution and average error probability of output.Also

in Rayleigh（one example of Nakagami） multipath channels

the numerical results of capacity are evaluated.It is proved that RAMC CDMA can transport higher bit rate services without extra bandwidth than general DS CDMA system

and the capacity is not too low.
