Title: METHOD FOR SUPPRESSING INTER-SUBCARRIER INTERFERENCE AND NOISE SIGNAL, AND ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING RECEIVER FOR PERFORMING SAME
Abstract:
A method for suppressing inter-subcarrier interference and a noise signal, and an orthogonal frequency division multiplexing (OFDM) receiver for performing the same are provided. Here, the method for suppressing, by the orthogonal frequency division multiplexing receiver, inter-subcarrier interference and a noise signal by using a symbol interference-free interval having no inter-symbol interference (ISI) in a guard interval (GI) comprises: a step of performing a summing operation between sample data of the symbol interference-free interval and sample data of the effective symbol interval, by using the signal to noise ratio (SNR) of the symbol interference-free interval and the SNR of an effective symbol interval corresponding to the symbol interference-free interval; and a step of performing fast fourier transform (FFT) on fast fourier transform input data configured by including the summed sample data in the effective symbol interval.
