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.)

minimum mean square estimator log spectral amplitude is an anhanced technique of the minimum mean square estimator developed by Ephraih and Malah in 1985.It is used for signal processing by improving the Signal to noise Ratio.

对m序列的原理、结构、性质进行了分析,在Matlab中采用编程和Simulink动态仿真功能2 种方式实现了m序列.仿真实验表明,这2种方法简单,易于实现,可移植性较强,具有可行性和 设计的合理性. (The principle of the m sequence, structure and properties were analyzed in Matlab, Simulink using dynamic programming and simulation capabilities are 2 ways to achieve the m sequence. Simulation results show that these 2 simple and easy to implement, portability strong the feasibility and rationality of the design.)
