Abstract

Subband Adaptive Orthogonal Frequency Division Multiplexing (OFDM) constitutes an effective method of compensating for the frequency selective fading incurred by mobile receivers. The channel transfer function estimation error increases as a function of the Doppler frequency and of the subband modem mode signalling delay. This leads to a degradation of the system performance. In this contribution a 2D-MMSE channel-predictor is investigated as a means of compensating for these effects, which incorporates the scheme proposed in [I] into adaptive OFDM.
