GPS定位，在android4.4下编译通过，可供参考学习(GPS positioning, android4.4 compiler, available for reference study)

自己做的一个双馈电机的矢量控制，可以跑，PI参数和电机系数可以自行修改修改，波形会更好。(This is a DFIM FOC simulation program based on MATLAB simulink.It contains the SVPWM program.)

Matlab高斯信道条件下采用QPSK和8PSK时点到点通信系统的理论和统计所得的误码率和误比特率曲线。 删余卷积码的Pb性能仿真 加入信道编码模块，绘制误比特率曲线,其中信道为加性高斯白噪声，调试为QPSK； 进行软判决和应判决，和用3/4、7/8删余码进行编码等。(Matlab gaussian channel conditions using QPSK and eight PSK point to point communication system theory and statistical the error rate and bit error rate curve. Delete the convolution code more than Pb performance simulation Join channel coding module, draw bit error rate curve, which channel to additive gaussian white noise, commissioning for QPSK In the soft decision and judgment should be, and with more than 3/4, 7/8 delete code for coding, etc. )

各种雷达的回波信号模拟，有很好的参考价值，可以用来做雷达信号处理算法的研究

说明：  线性调频信号的仿真，在此基础上，结合频控阵，实现了频控阵和线性调频信号的结合，将结合后的信号作为欺骗干扰信号。(Based on the simulation of LFM signal, the combination of frequency control array and LFM signal is realized, and the combined signal is regarded as deceptive jamming signal.)

说明：  基带信号bpsk仿真，基带传输基本方波信号、sinc信号，对过程添加高斯白噪声，接收端用匹配滤波器进行接受，计算实际信号误码率，并于理论误码率进行比较(BPSK simulation of baseband signal. Baseband transmits basic square wave signal and sinc signal. Gaussian white noise is added to the process. Matched filter is used to receive the received signal. The error rate of actual signal is calculated and compared with the theoretical error rate)

基于接收信号强度的KNN室内定位算法，还有测试数据。适合初学者参考(KNN indoor positioning algorithm based on the received signal strength, as well as test data. For beginners)
