Abstract
A reduced co-channel interference television transmission system includes a transmitter that transmits a video signal dispersed in one sense and a receiver having a selectively reversible dispersal filter for recovering the transmitted signal. The transmitted signal includes data concerning the sense or direction of the transmitter dispersal filter. The data is received by the receiver and used to automatically select the correct sense of the receiver dispersal filter. A SAW implementation of a reversible dispersal filter is shown.
