与s1非相干的 信号s2 如何生成?
（matlab）求s1信号的非相干信号s2生成程序Pd=2000;Fd=1;Fs=4*Fd;R=0.5;Delay=5;M=4;x1=randint(Pd,1,M); x2=randint(Pd,1,M);y1=modmap(x1,Fd,Fs,'qask',M);[rcv_a1,ti]=rcosflt(y1,Fd,Fs,'fir/sqrt/Fs',R,Delay);s1=amodce(rcv_a1,10,'qam');与s1非
相干与非相干,主要看相干系数,在信号上体现在,只要两个信号的频率不一样,这两个信号就是不相干的.
x1=randint(Pd,1,M);
x2=randint(Pd,1,M);
这里产生均匀分布的随机整数矩阵,本身就是两个非相干的信号.
所以,后面的s2信号可以写成：
y2=modmap(x2,Fd,Fs,'qask',M);
[rcv_a1,ti]=rcosflt(y2,Fd,Fs,'fir/sqrt/Fs',R,Delay);
s2=amodce(rcv_a1,10,'qam');
