Patent ID: 7362793

Claim:
A spread spectrum base station for receiving a plurality of spread spectrum signals and a plurality of phased spread spectrum signals, said base station comprising: an antenna; a plurality of delay devices connected to said antenna, each delay device outputting a time-delayed spread spectrum signal; a combiner connected to said plurality of delay devices for combining the plurality of time-delayed signals and the plurality of phased signals, said combiner outputting a combined signal; a radio frequency/intermediate frequency (RF/IF) section connected to said combiner, said RF/IF section converting the combined signal into in-phase (I) components and quadrature-phase (Q) components; a plurality of despreaders connected to said RE/IF section, each despreader despreading the I and Q components of the combined signal into a despread signal; and a plurality of controllers, each controller connected to a corresponding despreader and a corresponding delay device, whereby each controller controls a single delay device and includes: a magnitude generator for generating a magnitude value from the despread signal, a memory for storing a previous magnitude value and a present magnitude value, and a comparator for comparing the previous magnitude value with the present magnitude value and outputting a comparison signal used to control said delay device.
