Hi,
Assuming that you send a Zero-Mean Gaussian signal through a channel which has White Non-Zero Mean Gaussian Noise but is Not Additive.
I say additive because the variance of the added noise is dependent on the input signal variance.
How can we measure the BER is we assume a QAM signal to be sent?
You can not use the formulas in the books.
They assume AWGN.
Any Hints or References!!!????
Thanks
