FFT

vb语言实现的卡尔曼滤波源程序,超级酷,建议下载(vb language Kalman filter source files, Super Cool, the proposed Download)

函数用于图象质量评价， 计算梯度均值，标准差，峰值(Function for image quality evaluation, and to calculate the gradient of the mean, standard deviation, peak)

多目标遗传算法求最佳值，通过加权的方式将多目标转为单目标(Multi objective genetic algorithm for optimal value)

不考虑多径干扰时在高斯白噪声和瑞利衰落信道条件下QPSK的调制解调过程， 并采用准分析法完成误码性能的计算。仿真过程包括仿真信号产成，滤波器设置，QPSK调制，加入高斯白噪声，通过锐利信道衰落，QPSK解调，误码率计算等几部分(Not consider multi-path interference at the white Gaussian noise and Rayleigh fading channel under the conditions of the QPSK modulation and demodulation process and the use of quasi-analysis method to complete the calculation of BER. The simulation process includes the middle class into a simulation signal, filter settings, QPSK modulation, by adding Gaussian white noise, through the sharp decline in channel, QPSK demodulation, bit error rate calculation and other parts)

说明：  此程序实现求任一信号的幅频响应，需知的参数有待求信号及其采样率。(The programme realize to get amplitude frequency response.)

create a function in neural network

说明：  基于matlab的多径信道下OFDM通信系统误码率仿真(Bit error rate simulation of OFDM communication system in multipath channel based on MATLAB)

图像处理，用于在MATLAB中播放AVI视频文件。附送标准AVI文件一枚。(Image processing, used to play AVI video files in MATLAB. With a standard AVI file.)

说明：  全相位FFT算法是天津大学的王兆华和候正信教授提出的，具有初始相位不变和有效防止频谱泄露的特性，在他的相关书籍上做过严格的证明，并有相应的matlab程序。(All-phase FFT algorithm is proposed by Professor Wang Zhaohua and Professor Hou Zhengxin of Tianjin University. It has the characteristics of invariant initial phase and effective prevention of spectrum leakage. It has been strictly proved in his relevant books and has corresponding matlab program.)
