Abstract:
A method for use in a spread spectrum communication system of steering antenna beams of a phased array receiver, the receiver having a set of phased array antennas, the method comprising:receiving a spread spectrum signal containing a plurality of channels by the set of phased array antennas;outputting timed versions of the received signal, each timed-version associated with a respective one out of said set of phased array antennas;producing a combined despread signal by combining and despreading each timed version of the received signal using a specific chip code sequence associated with a selected channel;determining a magnitude of the combined despread signal for obtaining a present and a prior magnitude;comparing the present magnitude with the prior magnitude; andadjusting a delay associated with the timed versions in response to the comparison so antenna beams associated with the set of phased array antennas are steered towards components of the spread spectrum signal with a highest combined magnitude.
