to define color of the image

matlab 实现PCA算法，可以输出识别率，有详细注释，值得一用(Face Recognition Using PCA algorithm procedure, with annotations, 88 recognition rate )

design cycloconverter 1/3 phase

设计一个采用 2ASK（OOK）调制的数字通信系统，给定载波频率为码元速率的2倍，产生二进制随机数据，并仿真其对应的 2ASK 调制波形，分析其频谱。所产生的调制波形加入不同信噪比的白噪声，再观察其波形和频谱变化。(Design of a use 2ASK (OOK) modulated digital communication system, a given carrier frequency is twice the symbol rate, to generate a random binary data, and simulate its corresponding 2ASK modulation waveform, the spectrum analysis. Modulated waveform generated by white noise with different noise ratio, and then observe its waveform and spectrum changes.)

说明：  用Matlab实现灰度图像SIFT（尺度不变特征变换）特征点的提取(Grayscale images with Matlab SIFT (Scale Invariant Feature Transform) feature point extraction)

语音信号处理仿真，采用谱减法，可以对强噪声背景下的语音信号进行去噪(Speech signal processing simulation, using spectral subtraction, you can voice signal under strong noise denoising)

本程序比较了LS(最小二乘）和最小均方误差准侧下OFDM信道估计的误码率，给出了LS及MESE实现的源程序，是信道估计初学者的理想参考资料(This procedure compares the LS (least squares) and minimum mean square error of quasi-lateral channel estimation of OFDM bit error rate, given the realization of the LS and the MESE source, channel estimation is the ideal reference for beginners)
