Abstract
A reciprocity-based precoding algorithm is provided that accommodates for the specific type of uncertainty arising from the delay in channel estimation as a function of the velocity of moving wireless communication devices (-). Account is taken of time delay from reference symbols previous sounding times as well as the velocity of the wireless communication devices (-) thereby providing an effective precoding scheme for beamforming.
