A NEW GCR SIGNAL AND ITS APPLICATION

The multipath reception of television image, commonly referred to as g host, is a widespread problem. The successful implementation of a ghos t canceling system requires that the transmitted video signal contains a training signal called a GCR signal. By comparing the received dist orted GCR signal with a stored reference GCR signal, the receiver can configure an appropriate channel compensating filter to cancel the dis tortion introduced in the transmission path. The joint development gro up in Korea developed Korean standard GCR(KGCR) based on the ternary s equence and carried out the computer simulation and the laboratory and field test.
