无线传感器网的leach协议的实现。基于matlab。。(Wireless sensor networks leach protocol implementation. Based on matlab. .)

说明：  伪随机序列发生、分析相关性，并作出初步判断的m程序；运行后的可见图形。(The pseudo-random sequence has, the analysis relevance, and makes the preliminary judgment the m procedure After movement eye diagram.)

基于SVM的手写数字识别及数字图像的特征提取(SVM-based handwriting recognition and digital image feature extraction)

SM系统matlab程序，传输天线、接收天线数量可调，信号调制方式可调，循环次数可调。最后生成BER性能曲线，并将不同SNR下的BER数据存储到mat文件中。(SM system matlab program, the number of transmission antennas, a receiving antenna is adjustable, adjustable signal modulation scheme, the number of cycles is adjustable. Last generate BER performance curve, and store data in different SNR BER under the mat file.)
