Multi-transmitter wide-area cellular broadcast communication system
Abstract
Abstract In a broadcast communication system, a plurality of transmitters (T₁, T₂, ... T M ) are located at different locations throughout a broadcast area for separately and synchronously broadcasting a common digital communication signal at a predetermined frequency over different signal paths, and a receiver (10, 12) located within the broadcast area receives the common digital communication signal separately broadcast by a plurality of the transmitters at the predetermined frequency over different signal paths and processes the received signal to reproduce the common digital communication signal without the effects of multipath and other channel distortions. The received signal is modified in relation to the broadcast signal by channel responses of the different signal paths; and the receiver includes an adaptive equalization filter (12) for processing the received signal inversely in accordance with a collection of the channel responses of the different signal paths to reproduce the common digital communication signal without the effects of multipath and other channel distortions. The accuracy of the filter in processing the received signal in accordance with the inverse of the collection of the channel responses of the different signal paths is enhanced by adapting the filter to reproduce a predetermined known common digital communication signal without the effects of multipath and other channel distortions.
