Abstract:
1. A spread spectrum base station comprising: a set of phased array antennas for receiving a spread spectrum signal containing a plurality of channels; at least one delay device for outputting at least one timed version of the received signal, each timed version associated with one of the phased array antennas; a despreader for producing a plurality of despread signals by despreading the at least one timed version of the received signal using chip code sequences associated with the plurality of channels; a combiner configured to combine the despread signals to form a combined despread signal; and a counter for adjusting a delay associated with the at least one timed version of the received signal based on a change in magnitude of the combined despread signal such that antenna beams associated with the set of phased array antennas are steered towards components of the spread spectrum signal with a highest combined magnitude.
