Hi Everyone,

i have the error "Unrecognized function or variable 'iN',

I don't know how to fix this problem. Thank you in advance for your help

code:

function [P]=simRangeData(N,iN,S,iS)
pwrSig=10.^(S/10); 
pwrNoise=10.^(N/10);
nRangeGate=iN(end);
voltNoise_I=zeros(nRangeGate,1);
voltNoise_Q=zeros(nRangeGate,1); 
I=length(iN);
iLead=1;
for i=1:I 
     iLag=iN(i); 
     voltNoise_I(iLead:iLag)=sqrt(pwrNoise(i)/2)*randn(iLag-iLead+1,1); 
      voltNoise_Q(iLead:iLag)=sqrt(pwrNoise(i)/2)*randn(iLag-iLead+1,1); 
      iLead=iLag; 
end
noise=voltNoise_I+j*voltNoise_Q; 
signal=zeros(size(noise)); 
I=length(iS); 
for i=1:I 
    pwrSwerling=exprnd(pwrSig(i),1,1);
    signal(iS(i))=sqrt(pwrSwerling/2)+j*sqrt(pwrSwerling/2); 
end
data=signal+noise; 
P=abs(data).^2;
