Title: Ntsc co-channel interference detectors responsive to received q-channel signals in digital tv signal receivers
Inventor: LIMBERG ALLEN LEROY
IPC: H04N5/44
Filed: 1997-10-02
Abstract: PURPOSE: A NTSC co-channel interference detector responsive to received Q-channel signals in digital TV signal receivers is provided to detect an interference of co-channel from a NTSC analog TV signal. CONSTITUTION: An NTSC co-channel interference detector detects the presence of an interfering NTSC signal in the received Q-channel signal that is orthogonal to the received I-channel signal, rather than detecting the presence of an interfering NTSC signal in the received I-channel signal. By determining whether or not a significant amount of NTSC co-channel interference accompanies the received Q-channel signal, it is inferentially determined whether or not a significant amount of NTSC co-channel interference accompanies the received I-channel signal, such as to cause too many errors in the trellis decoding of equalized received I-channel signal to be corrected by the Reed-Solomon decoder(40) following the trellis decoder(34). The accurate determination of co-channel NTSC interference levels is simplified, because essentially no direct bias arises from the quadrature-phase synchronous detection of the pilot carrier of the VSB AM digital television signal.
