代码说明:

%plot_Jakes_model.m 清除所有、 %关闭所有 %参数 fd = 100 ;Ts = 1e-6 ;%的多普勒频率和采样时间 M = 2 ^12 ;t = [0:M-1] * Ts;f=[-M/2:M/2-1]/(M*Ts*fd) ; Ns = 50000 ;t_state = 0; %渠道代 [h,t_state]=Jakes_Flat(fd,Ts,Ns,t_state,1,0) ; figure() ; %subplot(311) plot([1:Ns]*Ts,10*log10(abs(h))), %标题 ([" 杰克斯模型,f_d =",num2str (fd)"Hz、 T_s=",num2str(Ts),"s"]) ; 标题 ([" 杰克斯模型、 f_d=",num2str(fd),"Hz"]) ; axis ([0 0.05-30 10])、 xlabel("time[s]")、 ylabel("Magnitude[dB]") %subplot(323)、 hist(abs(h),50) ; %标题 ([" 杰克斯模型,f_d =",num2str (fd)"Hz、 T_s=",num2str(Ts),"s"]) ; %xlabel("magnitude")、 ylabel("Occasions") %subplot(324)、 hist(angle(h),50) ; %标题 ([" 杰克斯模型,f_d =",num2str (fd)"Hz、 T_s=",num2str(Ts),"s"]) ; %xlabel("phase[rad]")、 ylabel("Occasions") %自相关的通道 %{ temp=zeros(2,Ns) ; 为我 = 1:Ns j = i:Ns; temp1(1:2,j-i+1)=temp(
