FFT based single frequency interference accurate analysis method for OFDM signal

摘要：

Base on the results of FFT in OFDM demodulation, one new single frequency interference estimation scheme is proposed, which can estimate accurately the parameters of single frequency interference by analyzing two spectrum lines having higher energy than others. The complexity of the scheme is very low and its accuracy is much higher than that of the conventional scheme which using only single spectra line possessing maximum energy to estimate interference parameters. The simulation results indicated that the advantages of the new scheme.
