发明名称 SYSTEM FOR ECHO CANCELLATION COMPRISING A GHOST CANCELLATION REFERENCE SIGNAL
摘要 A system for echo cancellation for use in particular in television receivers. The system features a ghost cancellation reference signal which exhibits improved performance in noisy environments and which exhibits the flat and wide bandwidth necessary for effective channel characterization while exhibiting a higher and more evenly distributed amplitude versus time characteristic than that provided by known, non-cyclic ghost cancellation signals.
