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.)

fuzzy is a very useful technique in doing project works in the field of technology

功能软件 多多使用，多多下载，大家学习学习。不知道可用不(Your use of the software functions, a lot of downloads, we learn from. Do not know can not)

非常全面的matlab参考资料，方便新手入门以及查阅，可以用作示范教材。(Matlab very comprehensive reference material, easy for beginners as well as access to, can be used as demonstration material.)

主要是FRFT_OFDM的一些论文资料。(it mainly is some papers FRFT_OFDM)
