In this article, we introduce an algorithm to update the channel estimation in a flat fading channel. We assume an initial estimate of the channel is available, possibly from a training sequence, and the algorithm enhances this estimation so that longer packets and/or better BER can be achieved. The algorithm can work with any MIMO system but, when combined with VBLAST, can be implemented with a minor increase in hardware complexity. We assume flat fading with known maximum Doppler shift and SNR.
