九点差分格式，精度比五点差分要高，对于实现有限差分，是一个重要的程序(Nine-point difference scheme, the accuracy than the five-point difference is higher, for the realization of finite-difference, is an important procedure)

用双线性法设计巴特沃斯高通数字滤波器 基于汉宁窗的FIR数字高通滤波器设计(Method with bilinear Butterworth high-pass digital filter design based on Hanning window of FIR digital high-pass filter design)

通信信号中编解码技术的研究，通过生成OFDM信号，经过快速傅里叶变换与反变换，最后用16QAM解调，计算信噪比。(Communication signal encoding and decoding techniques, but by generating OFDM signals, through the fast Fourier transform and inverse transform, and finally with 16QAM demodulation, signal to noise ratio calculation.)

该程序是同步中的相位估计方法，该方法可以估计不同参数下的相位大小(The program is synchronized in phase estimation method which can estimate the parameters of the phases of different sizes)

This code expains bayesian particle swarm optimization method.All files have been written on matlab 2007a. This method has been explianed with various benchmark functions. This optimization method can be directly compared with other unconstrained optimization method like GA or pso for effieciency and speed.

matlab求解vrpsd问题,解压可运行(HGA-for-VRPSD, The VRP is a well known integer programming problem which falls into the category of NP Hard problems, meaning that the computational effort required to solve this problem increases exponentially with the problem size.)

离散型永磁同步电机滑模控制，采用锁相环实现角度估算，角度误差低，效果好。(PMSM_SMO_PLL,test is good.)

实现产生伪随机序列的部件 —— 线性反馈移位寄存器单元。 SFlog2为扩频因子的底数为2的对数值，cycle为PN序列的周期，其值为2^SFlog2。initial_state为移位寄存器的初始状态，generator_polynomial_coefficient为生成PN序列所需的本原多项式，对应于移位寄存器的连接向量。(The realization of pseudo-random sequence generated components- LFSR unit. SFlog2 factor for the spread-spectrum base 2 of value, cycle for the PN sequence cycle, its value is 2 ^ SFlog2. initial_state shift register for the initial state, generator_polynomial_coefficient to generate the necessary PN sequence primitive polynomial, corresponding to the shift register connection vector.)
