说明：  为了采集准确的心电信号，设计了一套基于瞬时心率信号抗干扰测量的方法，针对微弱并易受干扰的心电采样信号，进行有效地硬件以及软件滤波，通过软件数字滤波算法，得到真实的心率信号(Set based on the instantaneous heart rate signal immunity measuring method to collect accurate ECG, ECG sampling signal for the weak and vulnerable to interference, hardware and software filtering, digital filtering algorithm through software, get real The heart rate signal)

分数阶傅里叶集成算法，matlab语言，实测，好用！(integrated algorithm about Frft, matlab code, have been tested, the results are right.)

是研究临近空间等离子体信道的极其重要的程序，可以产生等离子体信道中的反射透射系数(The plasma sheath can absorbe, reflect and scatter the electromagnetic wave signal, causing the communication signal producing the phenomenon of attenuation, phase shift, dispersion and other effects, in severe cases it can interrupt the signal.)

用matlab 来仿真模糊pid控制器，对学习pid有一定的帮助(fuzzy pid controller)

本程序用于完成BPSK、QPSK、8PSK的调制仿真。并可任意扩展到MPSK和MQAM。程序分成三个部分：phase.m对基带码元序列进行脉冲成型，可选矩形脉冲，升余弦脉冲和平方根升余弦脉冲； model.m 为主程序，完成各种信号的基带星座图映射、脉冲成型和调制； command.m给出一个简单的频谱显示测试。(This procedure for the completion of BPSK, QPSK, 8PSK modulation simulation. Arbitrary and may be extended to MPSK and MQAM. Program is divided into three parts: phase.m symbol of the baseband shaping pulse sequences, optional rectangular pulse, the square root raised cosine pulse and raised cosine pulse model.m-based procedures, completed a variety of base-band signal constellation mapping , pulse shaping and modulation command.m given spectrum shows a simple test.)

matlab的一些基本代码，希望对大家有用(matlab some basic code, and hope to be useful)

卷积码与Turbo码的性能仿真对比，在AWGN信道和Rayleigh信道下。(Performace Comparison of Convolutional codes and Turbo codes under AWGN channels)

matlab在电子信息工程当中的应用，绝对值得专业下载，学习(professional download matlab in which the application of the Electronic and Information Engineering, definitely worth learning)
