HCM是模糊聚类，k均值算法 !!!!!!(hcm)

求冲激函数、阶跃函数及三角函数的小波变换、模极大线并求它们的李氏指数(Demand impulse function, step function and trigonometric functions of the wavelet transform modulus maxima lines and seek their Lyapunov exponent)

用Matlab产生单双极性的NRZ和RZ码型(Using Matlab generated Mono polar NRZ and RZ format)

create modulated BPSK signal

这个程序能够降低OFDM的PAPR，是一个初始的程序，在这个基础上可以根据需要有很多改进(Reducing the Peak-to-Average Power Ratio of Multicarrier Modulation by Selected Mapping)

考虑一个线性自适应均衡器的原理方框图如《现代数字信号处理导论》p.275自适应均衡器应用示意图。用LMS算法实现这个自适应均衡器，画出一次实验的误差平方的收敛曲线，给出最后设计滤波器系数。一次实验的训练序列长度为500。进行20次独立实验，画出误差平方的收敛曲线。给出3个步长值的比较。(consider a linear adaptive equalizer block diagram as the principle of "modern digital signal processing" Introduction to the p.275 adaptive equalizer application schema. LMS algorithm with the adaptive equalizer, painted a square experimental error of convergence curve, given final design filter coefficients. Experimental a length of the training sequence to 500. Conduct 20 separate experiments, painted square error of the convergence curve. Given three step-value comparisons.)

very useful book about MIMO-OFDM wireless communications with matlab

this code is usefull to calcule the hydraulics properties for a given cross section or batymetric. Also plot the manning properties vs de hydraulic depth
