实现了卷积编码和维特比译码，也有简单的BPSK调制解调过程。-Achieved a convolution coding and Viterbi decoding, but also a simple BPSK modulation and demodulation process.

说明：  X2 software for something is good if you know that xD

说明：  整流器，dq坐标系，电压外环控制，pscad仿真(simulation of the rectifier in dq-frame)

说明：  矢量控制的永磁同步电机Simulink仿真模型，亲测可运行，多个模型。(Vector controlled permanent magnet synchronous motor Simulink simulation model, pro test can run, multiple models.)

S变换时频域滤波是一种二维的时间域—频率域的分析方法，此程序通过对信号进行时频域转换，通过分析干扰信号的时间与频率的分布范围，设计相应的滤波器进行滤波可以有效的去除干扰，又因为S变换的是无损的可逆的因此对信号没有损伤。(S transform time domain filtering is a two-dimensional time domain - frequency domain analysis method. By analyzing the time and frequency domain of the signal, by analyzing the distribution range of the time and frequency of the interference signal, the corresponding filter can be designed to remove the interference effectively, and because the S transform is nondestructive and reversible. There is no damage to the signal.)

说明：  极化码的基础编译码程序,适合初学者学习使用(The basic compiler of polarization code is suitable for beginners to learn and use)

说明：  空气耦合超声传感器的接收信号掺杂有大量噪声信号，根据传感器的参数设计匹配带通滤波器，提高接收信号的质量。(The received signal of air coupled ultrasonic sensor is adulterated with a large number of noise signals. According to the parameters of the sensor, a matched band-pass filter is designed to improve the quality of the received signal.)

It is an iterative algorithm that starts with an arbitrary solution to a problem

说明：  自己做的FFT分析程序，自己生成一个信号，利用FFT函数进行FFT分析，并画出频谱图。(FFT analysis program, self generated a signal, FFT function using FFT analysis, and draw the spectrum.)

模拟地震合成记录，仅供信号分析课程参考。程序执行完毕后，生成两个xls文件，Ricker.xls中是雷克子波，Seis.xls中是地震合成记录。(Simulated seismic synthesis record, reference only to the signal analysis course. Program execution is completed, generating two XLS files, Ricker.xls is Ricker wave, Seis.xls is a synthetic seismogram.)
