Abstract

We present an improved equalizing scheme to be used with orthogonal frequency division multiplexing (OFDM) systems in multipath channels with frequency offset and phase noise. We compare the performance of this method with methods that have been proposed to be used earlier with OFDM. For the performance evaluation we apply a random walk phase noise model with a typical terrestrial TV multipath channel
