Abstract
A ghost image cancellation technique for video signals received from multipaths during transmission of a TV signal over a transmission channel. In one example embodiment, an apparatus computes edge parameters of synchronization signals received from each of the multipath video signals. The edge parameters are then used to select an input video signal. The selected input video signal along with the computed edge parameters are then used to remove remaining video signals from the video signals received from the multipaths to cancel ghost images.
