关于无线信道的多普勒谱 无线信道中的多普勒谱有一种经典谱请解释产生这种谱形状的机理；

N=512;                        
fm=100;
for j=3:(512-1)
   f(j)=-100+(j-1)*200/(N-1);
   SEZ(j) = 1.5/(pi*fm*sqrt(1-(f(j)/fm)^2));
end
f(2)=-99.99;f(N)=99.99;
SEZ(2) = 1.5/(pi*fm*sqrt(1-(f(1)/fm)^2));
SEZ(N) = 1.5/(pi*fm*sqrt(1-(f(N)/fm)^2));
SEZ(1)=0;
SEZ(N+1)=0;
plot(-256:256,SEZ);
