BER verses SNR in ofdm with amplifier: The BER performances of OFDM systems over the AWGN channel are given by the BER where N=512. We see that SNR required for BER=10-3 No channel coding scheme is adopted. Therefore, BER is a bit higher. The results with 16 QAM show that the required Signal to Noise Ratio (SNR) for BER=10-2 is almost the same. This is because the noise is the dominant.
