Hello!

I have an AWGN channel model (for single user)
The noise is: nu~N(0,sqrt(N0)) 0 mean and sqrt(N0) standard deviation, where
N0 is the noise energy. In my case SNR=1/N0.

How can I calculate the theoretical Bit error rate?

Thank you
Thommer
 

Theoretical BER

It depends on the data format.
In the case of binary antipodal transmission, the theoretical performance for optimal receiver is erfc(sqrt(Eb/No))/2, where Eb is the bit energy, No is the noise power spectral density [Watts/Hz], and erfc() is the complementary error function.

Re: Theoretical BER

Hello!
Thanks for your andwer!
I'd like to transmit binary data e.g {-1,1}. If the noise has 0 mean and
sqrt(N0) standard deviation, and Eb=1 then is that suitable calculation you
wrote me for theoretical BER?
