考虑时变系统，采用遗忘因子递推最小二乘法进行参数识别(The time-varying system is considered, and the forgetting factor recursive least square method is used to identify the parameters)

说明：  使用LS算法对OFDM的信道进行估计，该算法估计行道计算量小，但是容易受到噪声的影响。(The OFDM algorithm is used to estimate the channel of OFDM. The algorithm estimates that the calculation amount of the road is small, but is susceptible to noise.)

GPS接收机中的卡尔曼滤波，经过测试！程序可以跑通！适合初学者！(Kalman filter in GPS receiver tested! The program can be run through! For beginners!)

说明：  永磁同步电机滑膜FOC控制，已调试可以正常运行(Permanent magnet synchronous motor slip film FOC control, has been debugged and can run normally)

matlab 应用图像处理知识，实现对数字的识别，识别率高(Matlab applies the knowledge of image processing to realize the recognition of the numbers and the high recognition rate)

64QAM using CMA algorithm

说明：  Goertzel算法是DTMF信号检测的核心,它利用二极点的IIR滤波器计算离散傅立叶变换值,快速有效的提取输入信号的频谱(Goertzel algorithm is the core of DTMF signal detection. It uses the two-pole IIR filter to calculate the discrete Fourier transform value, and extracts the spectrum of input signal quickly and effectively.)

说明：  单频信号实现频率估计，经典算法MRIFE(frequency estimation)

模拟gps信号的产生，基本功能已经实现，没有问题(sample qt)

能实现GPS时间到UTC时间的相互转换，测试过正确(Can realize GPS time to UTC time transformation between proper test)
