摘要
CDMA是实现多速率最主要的多址接入技术。针对基于可变处理增益的 CDMA方案 ,分析了不同速率发射功率的控制、信道调制、多址干扰环境下的信噪比和误码率。在 SPW上对多种速率、多个用户的同时传输的误码率特性进行了仿真。
CDMA systems are the main multiple access technology, which can carry out the multi rate transmission. In this paper, power control by different rate, channel configuration and SNR & BER under multiple access interference are analyzed by multi rate transmission scheme of CDMA on multi processing gain,and system probability of error under multi rate for the numbers of different rate users on SPW(Signal Processing Workshop is simulated.
