Abstract :
A broadcast ghost-canceling reference signal that will enable digital signal-processing circuits in TV sets to erase multipath distortions is discussed. A typical receiver ghost-canceling system, consisting essentially of a channel identifier and ghost-canceling filters, is described. Factors affecting the choice of a ghost-canceling reference (GCR) signal as a standard are examined. Results of field tests of five GCR systems proposed as US standards are reported.<>
