Abstract

OFDM is promising technology and has approved for various wireless system like 4G mobile system, Wireless Local Area Network (WLAN), Wimax etc. But due to carrier frequency offset (CFO) causes from Doppler spread and drift in local oscillator frequencies of transceiver leads to inter carrier interference (ICI). The ICI is the biggest limitation of OFDM system. In this paper, an optimized sinc power pulse (OSPP) for mitigation of ICI from OFDM system is proposed. The proposed method is compared with existing sinc power pulse (SPP) method in terms of carrier to interference ratio (CIR) and bit error rate (BER) in additive white Gaussian noise (AWGN) channel and results show that proposed method is better.
