A new GCR signal and its application

The multipath reception of television image, commonly referred to as ghost, is a widespread problem. The successful implementation of a ghost canceling system requires that the transmitted video signal contains a training signal called a GCR signal. By comparing the received distorted GCR signal with a stored reference GCR signal, the receiver can configure an appropriate channel compensating filter to cancel the distortion introduced in the transmission path. The joint development group in Korea developed a Korean standard GCR (KGCR) based on the ternary sequence and carried out computer simulations and the laboratory and field tests.>
