Orthogonal Frequency Division Multiplexing (OFDM) is the important modulation of choice for fourthgeneration broadband multimedia wireless systems. This paper is focused on the problem of reducing the intercarrierinterference (ICI) and signal to noise ratio in the transmission over OFDM using various pulse shaping methods. Here we have performed a detailed performance comparison of various pulse shaping functions used in OFDM System with Carrier Frequency Offset. They appear to be suitable for transmission in OFDM systems with carrier frequency offset. The results obtained by analysis show that the performance improvement over conventional pulse shapes, are significant for reducing average intercarrier-interference (ICI) power and increased ratio of average signal power to average ICI power (SIR).

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.
