ABSTRACT:
An interference contribution associated with a selected subcarrier of a plurality of subcarriers associated with a previously transmitted OFDM symbol or a current OFDM symbol is determined. A fast Fourier transform (FFT) output for the current OFDM symbol is also determined. The interference contribution is subtracted from the FFT output of the current OFDM symbol to form a modified FFT output.
