- W2356188759 abstract "Orthogonal frequency division multiplexing(OFDM) is a promising technology and has been approved for various wireless systems. However,inter-carrier interference(ICI) occurs in OFDM due to the carrier frequency offset(CFO) that results from Doppler spread and the drift in local oscillator frequencies of the transceiver. In this paper,a method for reducing ICI is proposed by using optimized sinc power pulse(OSPP). Using a parameter to optimize the sinc power pulse's sidelobe levels,the new OSPP method can reduce the intensity of ICI in OFDM system. Simulation results show that,compared with existing sinc power pulse(SPP) method,the OSPP outperforms the SPP in high mobility environment,and OFDM system with OSPP can achieve better bit error rate(BER) performance by 3 dB than that with SPP method when the normalization frequency offset is 0. 3 and the BER equals to 10-5." @default.
