matlab编写的模拟滤波器的设计，经运行完全正确！(matlab filter design simulation prepared by running completely correct!)

matlab实现fisher判别，对于统计方面有重要的应用，适合初学者学习(fisher discriminant matlab realize, for statistics has important applications, suitable for beginners to learn)

一个用循环谱原理给出的计算程序,可以画出信号的图形(a cyclic spectrum )

说明：  C高级编程，是提高的好书，希望大家认真阅读，我还会陆续发资料(C high-level programming)

阵列天线设计，提供方向图示意，计算阻抗等，很适用于初学者(array antenna design)

说明：  IIR滤波器设计 在设计一个IIR数字滤波器时，我们根据指标先写出模拟滤波器的公式，然后通过一定的变换，将模拟滤波器的公式转换成数字滤波器的公式(IIR filter design in the design of an IIR digital filter, we first write the analog filter based on index formula, and then through a certain transformation, the analog filters into digital filters equation formula)

说明：  GSM系统卷积码和交织编码在突发信道和AWGN信道误码特性及其比较(GSM system convolutional code and interleaved coded in the emergency channel and AWGN channel error characteristics and comparison)
