自编小程序，希望大家多多指导！！！！！！！小弟谢了(self small procedures in the hope that Members can guide! ! ! ! ! ! ! The younger Xie)

Instruction format. See the instruction format spec for details.

遗传算法具有强大的全局优化能力，并行计算的快速收敛性(Genetic algorithm has strong global optimization ability and fast convergence of parallel computing)

采用小波包算法进行压缩，小波树的确定则是根据不同的信息论准则，以达到分解系数表达的信息密度最高(Algorithm using wavelet packet compression, wavelet tree to determine if information theory is based on different criteria to achieve the decomposition coefficient expressed the highest density of information)

说明：  用matlab实现拟合的几个例子源码， ％x,y应是原始数据，下面的数据仅是为了说明问题而自设的示例数据。(Matlab fitting used to achieve a few examples of source code, x, y should be the raw data, the following data only to illustrate the problem of sample-based data.)

frft.快速分数阶傅里叶变换函数。调频信号分析的有力工具。(function of frft)

rs（255，239）码基于matlab编码，c语言译码，仿真性能优异(rs encoding with matlab,and decoding with c)

伪Wigner-Ville分布对实验采集外圈故障的振动信号进行分析，看出信号存在故障引起的冲击分量(The pseudo Wigner-Ville distribution is analyzed to the vibration signal of the outer ring fault, and the impact component caused by the signal is found.)

This is an implementation of GPS_CA code which is simulated under Matlab.
