Abstract
An apparatus and a method for receiving and transmitting information from an array of adaptive antenna elements, wherein a predictive filter supplies an estimate of received signal samples likely to be received in a burst immediately preceding a transmission. Combination of this estimate with received signal samples obtained from actual (historically received) signals, received over a predetermined number of frames, yield estimates of optimum beamforming coefficients for application to data for transmission from an adaptive array of antenna elements. As such, available processing time for obtaining the beamforming coefficients is increased.
