Pixel classification code using K-Nearest Neighbor Classifier.Here three pixel values of color image are taken as training sample.Color based segmented image was used to classify the object into three classes.

这是用matlab写的一个corner detector, 效果比现在流行的Harris，susan，CSS等效果要好。 Matlab 确实如此，效果很好，不管是边缘还是角点 (Algorithm is derived from: X.C. He and N.H.C. Yung, Curvature Scale Space Corner Detector with Adaptive Threshold and Dynamic Region of Support , Proceedings of the 17th International Conference on Pattern Recognition, 2:791-794, August 2004. Improved algorithm has been included in A Corner Detector based on Global and Local Curvature Properties and submitted to Optical Engineering)

OFDM具有很强的抗多径和抗频率选择性衰落的能力，并且可以传输高速数据，这里以DVB_T（2k模式）为例分析其加信道厚的信号频谱及信道对OFDM中频信号的影响。(The purpose of this programme is to provide Matlab code to simulate the basic processing involved in the generation and reception of an OFDM signal in a physical channel and to provide a description of each of the steps involved. For this purpose,we shall use, as an example, one of the proposed OFDM signals of the Digital Video Broadcasting (DVB) standard for the European terrestrial digital television (DTV) service.)

pre_distrion源程序，smilink源程序，可以对初学者有一定的帮助。(pre_distrion source, smilink source, can be helpful for beginners.)

关于gps的kalman滤波程序段，很有用的，呵呵(Kalman filter on the gps program segment, very useful, huh, huh)

说明：  二进制相移键控在恶劣信道环境下作为OFDM的载波调制方式的误码率对比(Binary phase shift keying in bad channel environment as a carrier OFDM modulation BER Comparison)
