Abstract:
Disclosed is a method for suppressing an inter-carrier interference and noise signal, and an orthogonal frequency division multiplexing receiver for performing the same. Here, a method for an orthogonal frequency division multiplex (OFDM) receiver to suppress an inter-carrier interference and noise signal by using a symbol interference free interval without inter-symbol interference (ISI) in a guard interval (GI) includes: performing a weighting operation between sample data of the symbol interference free interval and sample data of the effective symbol interval by using a signal-to-noise ratio (SNR) of the symbol interference free interval and an SNR of an effective symbol interval corresponding to the symbol interference free interval; and performing a fast Fourier transform (FFT) on FFT input data configured by including the weighting-operated sample data into the effective symbol interval.
