摘要 提出了 RAKE接收机的可变处理增益系统 ,分析了各种业务在不同概率情况下 ,双速率及三速率可变处理增益系统在瑞利信道下的性能。实验结果表明 ,随着分集支路数增加 ,系统容量大为提高 ,且在相同分集支路情况下 。 A variable process gain DS-CDMA system with RAKE receiver is presented and the different traffic with different probability in Rayleigh channel is analyzed. The experiments show that with the increase of diversity branch number, the system capacity improves greatly. And on condition of same diversity branch, increasing the probability of low speed services will improve the performance of the system.
