ABSTRACT:
An embodiment of the present invention provides a method for communicating in a wireless personal area network, comprising using adaptive beamforming configured for a low-rate mode for reliable low-rate communications and a high-rate mode for high-rate communications and using a fast algorithm to perform antenna beamforming for the high rate mode, wherein the fast algorithm includes training performed on a block-by-block basis with decision feedback from a receiver (RX) to a transmitter (TX) about the usefulness of further training stages.
