Abstract :
The paper deals with transmission of OFDM-BPSK signals over time-selective fading channels. The carrier frequency offset due to Doppler shifts is taken to be the main reason for the channel time-selectivity. Closed form analytical relation for bit error rate (BER) determination is derived enabling efficient evaluation of the inter-carrier-interference (ICI) effects introduced by the channel time-selectivity.
