Abstract:
A spread spectrum base station, the base station having a set of phased array antennas, the set of phased array antennas for receiving a spread spectrum signal containing a plurality of channels, the base station comprising:a delay device for outputting timed versions of the received signal, each timed version associated with a respective one out of said set of phased array antennas; a despreader and a combiner for producing a plurality of despread signals by despreading each timed version of the received signal using chip code sequences associated with the plurality of channels and combining the despread signals as a combined despread signal; a magnitude device for determining a magnitude of the combined despread signal for obtaining a present and a prior magnitude; a comparator for comparing the present magnitude with the prior magnitude; and a counter for adjusting 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.
