Base station having a set of phased array antennas
Abstract
A spread spectrum base station for receiving a plurality of spread spectrum signals and a plurality of phased spread spectrum signals includes an antenna and a plurality of delay devices connected to the antenna, each delay device outputting a time-delayed spread spectrum signal. A combiner is connected to the plurality of delay devices for combining the time-delayed signals and the phased signals, the combiner outputting a combined signal. An RF/IF section is connected to the combiner and converts the combined signal into in-phase (I) components and quadrature-phase (Q) components. A plurality of despreaders are connected to the RF/IF section, each despreader despreading the I and Q components of the combined signal into a despread signal. A controller is connected to each of the despreaders and controls a corresponding delay device.
