    How to calculate the theoretical BER?

    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?
