I want to create a complex gaussian noise CN(0,N0/2),which code is correct? noise=(randn(1,n)+1i*randn(1,n))*sqrt(N0/2) or noise=(randn(1,n)+1i*randn(1,n))*sqrt(N0/2)*sqrt(1/2) %sqrt(1/2) is normalized Which is right?

Which is right for complex noise CN(0,N0/2)?

'Pends on what you think CN(0,N0/2) means???
