文章中主要阐述了PN码的捕获，并对以前的各种捕获方法进行了改进。得出了基于FFT的快速捕获算法！(Abstract-A FFT-based parallel acquisition algorithm for Direct Sequence/Spread Spectrum radio navigation system is studied to solve long PN code acquisition using serial method. Frequency domain analysis of FFT to acquire signal is applied in this paper and state transfer function is used to derive the expression of average acquisition time.)

源码，非常实用，里外都是经过上机调试的源码，可以直接使用！(Source, very useful, both inside and outside the machine through the source debugger, you can directly use!)

不同方法估计协方差矩阵的Capon波束形成,以及多点约束的Capon波束形成和方向图，自己运行效果很好。(Different methods of estimation covariance matrix Capon beamforming, and multi-point constraints Capon beamforming and direction maps, run their own good results.)

本程序可以对一个模拟信号进行数字化，使用的是PCM即脉冲编码调制，其结果是将样值转化为8位PCM编码。现今语音编码大多数采用这类编码方法(This procedure can be an analog signal to digital, using pulse code modulation or PCM, and the result is kind of value will be translated into eight PCM coding. Most of the current speech coding to adopt this type of coding method)
