MMSE Channel Prediction Assisted Symbol-by-Symbol Adaptive OFDM
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 both as a function of the Doppler frequency and that of the subband modem mode signalling delay. This leads to a degradation of the system’s 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 [1] into an adaptive OFDM scheme.

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 both as a function of the Doppler frequency and that of the subband modem mode signalling delay. This leads to a degradation of the system’s 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 [1] into an adaptive OFDM scheme.
