A windowing mechanism for processing an OFDM symbol is presented. The windowing mechanism (86, 92, 94) applies an apodizing window function having the property Wj + W(FFTSIZE/2+j)=constant, where FFTSize is the size of the FFT sample, to a received OFDM symbol sample and a time-offset version of th e OFDM symbol sample to produce sets of window values. The time-offset sample is offset from the original symbol by one half the symbol period. The time-offs et windowed sample is shifted (88) into realignment with the windowed original symbol. Corresponding ones of the windowed values are summed (90) together t o restore the windowed symbol to its original form.
