systemview通信原理仿真2ASK(OOK)信号的解调(systemview Communication Principles Simulation 2ASK (OOK) signal demodulation)

里面包含cdma和ofdm两个方面的程序，非常难得的经典例子(Cdma and OFDM which contains two procedures, a very rare example of a classic)

M=63 J=(M-1)/2 Wp=0.5*pi Ws=0.6*pi Np=100 Ns=100 weightp=1 weights=100 通带和阻带的加权系数 WpN=linspace(0,Wp,Np) WsN=linspace(Ws,pi-0.05,Ns) Wm=[WpN WsN] p=[ones(1,50),ones(1,50)/2] d=[p,zeros(1,Ns)] W=diag([weightp*ones(1,Np),weights*ones(1,Ns)]) C=cos(Wm*[0:J]) Q=diag(cos(Wm*0.5)) g=(W*Q*C)(W*d) g=g h=(g(J:-1:2)+g(J+1:-1:3))/4 h=[g(J+1)/4 h g(1)*0.5+g(2)/4] h=[h fliplr(h)] W=linspace(0,pi-0.1,512) H=freqz(h,1,W) plot(W/pi,20*log10(abs(H))) (filter design)

RLS算法,编写了MATLAB程序实现自适应干扰对消.给出信号实例,用于验证所编写程序的性能(RLS algorithm, written MATLAB program to achieve adaptive interference cancellation. Given the signal instance, used to validate the performance of the programming)

说明：  基于端射阵的平面阵列方向图研究，对端射阵进行优化，采用遗传算法。(Planar array of end-fire array pattern study based on the end-fire array is optimized using genetic algorithms.)

只是一个利用MATLAB实现同步数字锁相环仿真程序(Is just a realization of synchronous digital phase-locked loop using MATLAB simulation program)
