Hy,

I am using the BER-Tool (Bit-Errorrate-Tool) in Matlab. When I simulate with a QPSK-Modulation and an AWGN-Channel there is difference between the simulated BER and the theoretical-exact BER. The difference is about factor 100 with Eb/No = 10 dB. But the two curves should be the same in ideal simulation, shouldn't they? Does somebody have any explanation for this difference?

Thanks for any advice.
