特征提取SIFT算法，对放缩 旋转不变性使此算法的经典之处。模式识别的必会算法(SIFT feature extraction algorithm, scaling rotation invariance to the classic between the algorithm. Pattern recognition algorithm will be)

system control second ordem

典型的多项式快速傅里叶变换程序，现在只做到三阶，为初学者提供参考。(A typical polynomial fast Fourier transform program, now only do third-order, provide a reference for beginners.)

维纳滤波器程序主要适用于dsp系统下的运作和开发！(weina filter program )

说明：  利用PTS技术降低峰均比，并作出与未使用降低PAPR技术的CCDF对比图形(Comparing with OFDM system without PAPR reduction techniques,figure the CCDF using PTS technique.)

异步电机无速度传感器控制，包含三个文件，使用matlab内部电机模型(Induction motor speed sensorless control)

说明：  使用人工势场法APF完成机器人的避障及路径规划(Using APF to complete obstacle avoidance and path planning of robot)

说明：  经典MUSIC在均匀线阵的情况。本例给出了MUSIC算法估计出的算法图，从图中可以直接看到估计的角度。我们的仿真实验用的是8个阵列，2个接受信号。MUSIC算法的精度很高。(MUSIC classic in the case of uniform linear array. In this case gives the MUSIC algorithm to estimate the algorithm maps directly from the chart to see the estimated angle. Our simulation experiments using 8 arrays, two acceptable signals. MUSIC algorithm for high precision.)

广义互相关算法和最小均方自适应滤波法主要用于两路接收信号的时间延迟估计，进而利用几何方法对目标定位，常用于通信，雷达当中(broad cross-correlation algorithm and the minimum mean square adaptive filter for the two main roads to receive signals in the time-delay estimation, then use geometric method of orientation, used in communications, radar them)
