communication system is expected to increase the service, the quality improvement and also the capacity, using spread spectrum communication system is one of the method to fulfill that demand. This quality and capacity factor will depend on the number of user. In order to see the performance of the Wiener Filter on the MC-CDMA system, simulation method is used by increasing the Direct Sequence Spread Spectrum CDMA signal, with digital modulation QPSK

Rapid-Acquisition-of-Doppler-Shift-
本文提出了一种适用于低轨卫异扩频通信系统的多普勒频移快捕方法.该方法基于数字匹配滤波器及自动频率控制环路_利用数字匹配滤波器的囚码快捕特性及其输出主相关峰值对频偏的敏感性,缩短多普勒频移的
捕获时间.论文首先推导了多普勒频移的平均捕获时间表达式,然后根据数值分析结果得到了准最佳捕获判决策略,最后通过比较验证了该快捕方法相对于传统串行捕获方法在性能上的提高.
(This paper presents a low-orbit health for different spread spectrum communication system fast catching the Doppler shift method, which based on digital matched filter and automatic frequency control loop _ prisoners using digital matched filter code features rapid acquisition and the output of the main correlation peak frequency deviation of the sensitivity of the Doppler frequency shift to shorten acquisition time. paper first derive the mean Doppler shift acquisition time expression, then the numerical results obtained quasi-optimal capture decision strategies, and finally verified by comparing with the rapid acquisition method to capture the traditional method of serial improvement in performance.)
