GHOST CANCELLING REFERENCE SIGNAL GENERATION AND TRANSMISSION METHOD

摘要

(10) inserting a ghost cancelling reference signal having an amplitude and at least more than two pulses which is outputted from a ghost cancelling reference signal generating part into the established position of some line of a vertical blank of an image signal; (20) modulating the ghost cancelling reference signal inserted into the image signal in order to be appropriate for the channel characteristics; and (100) transmitting the signal outputted from the above step with 8 fields in sequence in order that a receiving terminal may receive one ghost cancelling reference signal.
