dtw的程序代码，可以实现动态时间对齐，自己编的，可以使用(dtw' s program code, dynamic time alignment can be achieved, their own code, you can use)

用costas环检测淹没在噪声和未知任何先验参数的正弦信号检测(with Costas Loop Detection drowned in the noise and any a priori unknown parameters of sinusoidal signal detection)

Random numbers in a given range. Prints N numbers between lo and hi.

This file includes vector controlled ı nductı on motor drive mdl.

涡旋光束，幂指数涡旋光束，新型光束，捕获粒子，特殊光学(Vortex beams, exponential vortex beams, the new beam, trapped particles, special optical)

信号为两个正弦信号加高斯白噪声，各正弦信号的信噪比均为10dB，长度为N，信号频率分别为 和 ，初始相位 ，取 ， 取不同数值：0.3，0.25。 为采样频率。分别用Levinson递推法和Burg法进行功率谱估计，并分析改变数据长度、模型阶数对谱估计结果的影响。(Signal into two sinusoidal signals applied Gaussian white noise, the SNR of each sinusoidal signals are 10dB, a length of N, respectively, and the signal frequency, initial phase, take, take different values: 0.3,0.25. It is the sampling frequency. Respectively Levinson recursion method and Burg method for power spectrum estimation, and change the length of the data analysis, the impact of model order estimation result spectrum.)

说明：  遗传算法的MATLAB程序 (MATLAB Genetic Algorithm procedure)

估计样本序列的自相关函数，并比较SBT，SMVDR，SAR，SMuisc，画出各估计结果 (The estimated autocorrelation function of the sample sequence, and compare the SBT, SMVDR, SAR, SMuisc, draw the estimated results)

RAKE接收机，一种能分离多径信号并有效合并多径信号能量的最终接收机。(RAKE receiver, a multipath signals are separated and eventually the receiver effectively combined multipath signal energy.)

说明：  采用RGB+K-means对路标进行提取，效果十分不错。(RGB+ k-means is adopted to extract road signs, and the effect is very good.)
