Abstract :
We present an improved equalizing scheme to be used with orthogonal frequency division multiplexing (OFDM) systems in time-variant channels. We compare the performance of this method with a method that has been used earlier with OFDM. For the performance evaluation we apply a widely used frequency non-selective fading mobile channel model with additive white Gaussian noise (AWGN)
