ABSTRACT:
A multi-channel transmitter (200) in accordance with the present invention overcomes the disadvantages of applying adaptive antenna array technology to multi-channel communication systems. The multi-channel transmitter includes a channel processing element (210), a plurality of radio frequency processing elements (206), and an antenna array (102). The channel processing element includes a channel processor adapted to receive a communication signal from a communication network, a splitter (216) coupled to an output of the channel processor for producing a plurality of substantially identical processed digital communication signal outputs. A plurality of gain and phase adjusters (214) in the channel processing element are coupled to the substantially identical processed digital communication signal outputs. An output of each phase and gain adjuster (214) is coupled to a plurality of up-converters (212), which each produce a digital intermediate frequency output. The plurality of radio frequency processing elements (206) are each coupled to an output of the digital up-converters (212). The radio frequency processing elements (206) each include a digital summer (224), a digital-to-analog converter (222), and a radio frequency processor (220). The antenna array has a plurality of antenna elements (104), each coupled to an output of the plurality of radio frequency processing elements (206).
