ABSTRACT:
A multi-function cellular television system includes transmitting antennas located in an array such that the transmitted signals of adjacent antennas are of substantially differing polarity. The system provides for a variety of two-way communication services including television, both public and private programming, digital two-way transmission, special video teleconferencing, radio programming and telephone services. A low power output coupled with a wide bandwidth in the 27.5 to 29.5 GHZ millimeter wave band region is employed along with very high Q filtering intermodulation and interference reduction circuitry. The system has the ability to transmit, retransmit and receive numerous simultaneous signals with little or no modulation distortion or interaction. Further reduction of distortion is achieved through the use of modulation diversity, frequency diversity and space diversity.
