摘要

研究了在加性高斯白噪声和干扰存在下，基于IS-95标准的码分多址(CDMA)蜂窝系统的误码率(BER)性能。对CDMA前向链路在噪声和干扰下的性能进行了评价。Rake接收器用于基于cdma(码分多址)的系统，可以组合多路径组件，这些组件是原始信号传输的延时版本。合并是为了提高接收端的信噪比，从而降低误码率。

BER Performance Analysis of CDMA Forward Link

The bit error rate (BER) performance of the Code Division Multiple Access (CDMA) cellular system based on IS-95 standard in the presence of an additive white Gaussian noise (AWGN) and interference has been investigated in this paper. The performance is evaluated under noise and interference for the CDMA forward link. Rake receiver is used in CDMA-based (Code Division Multiple Access) systems and can combine multipath components, which are time-delayed versions of the original signal transmission. Combining is done in order to improve the signal to noise ratio at the receiver and so reduced the BER.
