Abstract
Under the Orthogonal Frequency Division Multiplexing(OFDM) wireless mobile environment,the elimination of Inter-Carrier Interference(ICI) has been studied.Although some traditional ICI cancellation algorithms can achieve the elimination of certain effects,there is still a lack of accuracy and necessary mathematical analysis,etc.This paper,compared the former ICI self-cancellation algorithm,improved system model and proposed a new error rate analytical method with frequency offset and a lower ICI method in OFDM digital communication systems,which is group conjugate elimination algorithm.It also analyzed the realization of a mathematical method for this algorithm.Simulation results show the comparison of this method with other methods of Bit Error Ratio(BER) performance.
