DFT数字信号采集滤波器实例演示程序，很实用的一个小程序。(DFT filter digital signal acquisition example demo program, it is a small utility program.)

（7，4）系统循环码译码器 decode_out = cyclic_decoder(decode_in) 该系统循环码译码器的生成多项式是g(x) = x^3 + x + 1 输入参数decode_in是接收到的循环码字，是1×7的行向量；输出decode_out是解 码后的信息码字，是1×4的行向量。 函数运行时，同时画出接收循环码字和译出码字的波形图。 ( (7,4) system cycle Decoder decode_out = cyclic_decoder (decode_in) cyclic code decoder of the system generating polynomial is g (x) = x ^ 3+ x+ 1 input parameters decode_in is the received codeword cycle, the row is 1 × 7 vector output decode_out solution code is the information after the code word is 1 × 4 row vector. Function to run at the same time code word and draw a circle to receive the word of the translated code waveform.)

说明：  MATLAB在曲线拟合中的应用，主要有一元线性回归 ，多元线性回归，曲线回归等(Curve fitting in MATLAB application, there are multi-linear regression linear regression, curvilinear regression, etc.)

说明：  使用VC与MATLAB混合编程实现了一路波形信号的FFT变换，简单修改后可以应用于信号处理程序中，由于使用了混合编程，大大减少了代码编写工作量(The use of VC and Matlab MATLAB waveform signals all the way FFT transform, simple modifications can be applied to signal processing procedures, the use of hybrid programming, greatly reducing the workload coding)

1、系统仅处于训练状态。训练序列为2cos(2π×f1×n/fs)， 干扰为sin(2π×f2×n/fs)；序列长度为100个样点。 其中n=0…99，f1=1kHz，f2=2kHz，fs=8kHz。 2、采用LMS算法，均衡器输入为训练序列加上干扰，均衡器阶数为21阶，步长因子β=0.01。 3、在Matlab中编写浮点LMS算法，绘制均衡器的输出波形，并与训练序列进行对比。 (1, the system only in the training status. The training sequence is 2cos (2πf1n/fs), interference sin (2πf2n/fs) sequence length of 100 samples. Where n = 0 ... 99, f1 = 1kHz, f2 = 2kHz, fs = 8kHz. 2, using LMS algorithm, the input to the equalizer training sequence plus interference equalizer order is 21 bands, step factor β = 0.01. 3, the preparation of the floating-point LMS algorithm in Matlab, draw the output waveform equalizer, and with the training sequence comparison.)
