改善宽带PCS信道的非线性补偿算法

在数据高速传输时为了补偿信道失真，使用了分集接收和等量获取结合技术。对设置在分集支线上的具有补偿算法接收结构的DSSS BPSK系统，以SNR的平均比特误码率来评价其性能。给出了具有较高数据补偿能力的多级Tap修正算法。为评价提出了算法在实际系统应用实现，利用了美国JTC个人移动通信用RF信道特性和系统应用模型标准，用平均比特误码率收敛速度进行了比较与分析。

An improved nonlinear compensation algorithm in broadband PCS channel

The diversity reception and the equal gain combining technique were applied to the compensation of the distortion of channel, which occured in transmission of data at rapid speed. DSSS BPSK system which has the receiving structure with the compensation algorithm was formed on the diversity branch, and the characteristics of the system were evaluated at the view point of the average bit error rate due to the SNR. In addition, the multi-tap update algorithm which is superior to compensation capacity of data was suggested. Moreover, using the PCS RF channel characterization of JTC of America and system deployment model standard, the suggested multi-tap update algorithm was compared and analyzed with the view-point of the average bit error rate and convergence speed for evaluating the realistic efficiency of the system.
