BPSK

the comb pilot aided channel estimation in ofdm modulation is considered. the power of pilot subchannels is under the control. The data experience frequency selective channel then the AWGN noise is added to make the situation worse. The bit error rate is ploted versus SNR.

ofdm snr is designed for signals
