自适应算法的程序，用matlab语言编写，属于现代信号处理方法。(Adaptive algorithm of the program, with the matlab language, belongs to modern signal processing methods.)

在libsvm平台下，用RBF核函数和polynomial多项式核函数结合，形成新的混合核函数，求验证其正确性(libsvm kernel of RBF and ploynomial )

说明：  遗传算法 多目标优化算法，SPEA2 主要流程：1：首先初始化一个archive的集合P1，以及一个常用的population的集合P。设置P1的大小是N1，P的大小是N。初始的时候P1是空的，而P是已经初始化好的种群个体。 2：对P1进行评价，选出来里面的pareto front为1（下面用PF1来代替了）的个体，copy到P1中，如果PF1的数量大于N1的话，这个接下来再说，目前假定PF1的数量小于N1。(Genetic algorithm, multi-objective optimization algorithm, SPEA2 Main process: 1: first, initialize a set P1 of archive and a set P of popular. Set P1 to N1 and P to n. At the beginning, P1 is empty, and P is the initialized population. 2: Evaluate P1, select the individual whose Pareto front is 1 (Pf1 is used to replace it below), copy to P1, if the number of Pf1 is greater than N1, then let's talk about it. At present, it is assumed that the number of Pf1 is less than N1.)

两个频率的凹口滤波对消干扰噪声，效果很好。希望大家仿真实验。(Two frequency notch filter to eliminate interference noise, the effect is very good. I hope everyone simulation experiments.)

使用MATLAB 代码完成COSTAS环对QPSK调制的解调载波频率的跟踪(Use MATLAB code completion COSTAS loop tracking of QPSK modulation carrier frequency demodulation)

说明：  应用电导增量法，实现光伏电池最大功率跟踪。(Achieve maximum power tracking of photovoltaic cells)

cpm调制解调实现,关联长度为3，调制指数和进制都可调，解调使用vitebi方法(cpm modem realize, correlation length for the 3, modulation index and the band are adjustable demodulation method using vitebi)

GPS卫星定位 利用广播星历计算卫星位置(Calculated using satellite position broadcast ephemeris)

基于matlab的一维条形码识别程序，条码为通用的EAN一13条码 (The bar code recognition program based on MATLAB)

说明：  对于给定的滤波器参数，利用脉冲响应不变性法设计数字低通滤波器，并绘出了设计后的数字滤波器的特性曲线。(This code uses impulse invariant method to design a digital low-pass filter under given filter parameters,then it plots the designed filter s characteristic curve.)
