一种时分的导引辅助的信道估计方法

x=0:10:100;
y=x;
Velocity=120;
LightSpeed=3*10^8;
Frequence=1*10^8;
WaveLength=LightSpeed/Frequence;
Fd=Velocity*10^3/3600/WaveLength;
hold off;
for i=1:length(x)
    SNR=x(i);
    sim('BPSK_ER');
    y(i)=mean(BitErrorRate.signals.values);
end
semilogy(x,y);
hold on;
for i=1:length(x)
    SNR=x(i);
    sim('siso');
    y(i)=mean(BitErrorRate.signals.values);
end
semilogy(x,y,'r');
grid on;
