Nyquist Pulse-shaping is one of the methods used to mitigate the effects of frequency offset in OFDM system which result in intercarrier interference (ICI). In this paper, the performance of coded OFDM(COFDM) with various Nyquist pulse shaping over AWGN channel with carrier frequency offset (CFO) are investigated. It is observed from simulation results that the Franks pulse outperforms all Nyquist pulses considered here in term of BER performance. Numerical results for ICI power reduction show that Franks and DJ pulses are quite similar, and outperform other pulses considered in this paper.
