    摘要： Enhanced wireless speeds are obtained using multiple transmission beams. In one example a transmitter sends data packets through an antenna array using multiple spatial beams and a plurality of analog converters. A receiver receives feedback from a remote station, the feedback including a quality measure of data packets received from the transmitter. A processor to controls transmission parameters of the transmitter using the feedback, the processor having a plurality of states, in a first channel analysis state, the processor determining a beam-forming vector for the antenna array, in a second beam search and training state, the processor determining pre-coding coefficients for the data packets, and in a third high rate transmission state, the processor providing pre-coded data packets to the transmitter for transmission, wherein the processor transitions from the third state to the first state upon receiving a reduced quality measure from the remote station.

    摘要： Enhanced wireless speeds are obtained using multiple transmission beams. In one example, a transmitter has a signal processor to receive a plurality of data streams, a plurality of analog converters each coupled to the signal processor to receive the plurality of data streams from the signal processor and to modulate the data streams onto carrier waves, and a plurality of phase shifters each coupled to an analog converter to each receive a modulated stream. A first antenna is coupled to more than one of the plurality of phase shifters to receive the modulated data stream from each phase shifter and transmit it on its respective carrier wave, and a second antenna is coupled to receive at least one modulated data stream and transmit it on its respective carrier wave.
