implementing midpoint filter

说明：  标准遗传算法与多种群遗传算法Matlab代码，求解函数最值，GA包含交叉变异。多种群遗传算法MPGA包含移民操作。(the standard genetic algorithm and a variety of group genetic algorithms matlab code to solve the function maximum, GA contains cross variation. multiple group genetic algorithms MPGA contain immigration operations.)

BPSK调制方式 产生信号，希望那个对大家有所帮助(BPSK modulation signal, in the hope that all of you to help)

系统辨识，通过输入PRBS，由3种模型，输出进行比较，从而辨识各个类别的系统(System identification, through the input PRBS, by three kinds of model outputs are compared to identify the various types of system)

ALOHA算法的仿真，对于算法的过程用mutlab进行了仿真(Frame slot ALOHA algorithm simulation)

matlab禁忌搜索算法的源程序，内含 TS_TSP.m TS_TSP TSP_DATA.m(Matlab tabu search algorithm source program)

基于802.11a的物理层协议的OFDM传输系统的matlab仿真及一些源代码(Based on the 802.11a physical layer protocol of the OFDM transmission system simulation and some of the matlab source code)

IEEE33节点电力系统前推回代潮流算法(IEEE33 node power system load flow algorithm forward and backward substitution)

说明：  滚动轴承故障诊断是机械故障检测中一个重要方面。使用小波包分析和包络分析相结合的方法提取轴承微弱振动信号, 克服了传统包络分析方法易丢失信号有效成分的缺点。包络信号的细化谱较好体现了轴承故障信息。(Bearing Fault Diagnosis of mechanical fault detection in an important aspect. The use of wavelet packet analysis and envelope analysis method of combining extracts bearing vibration signal weak to overcome the traditional envelope analysis method easy to lose the signal disadvantage of the active ingredient. Refinement of the envelope signal spectrum better reflects the bearing fault information.)
