Abstract (en)

[origin: WO2005006750A1] A digital broadcasting transmission/reception system having an improved receiving performance and a signal processing method thereof. The transmission system includes a FEC encoder encoding an incoming signal according to a certain FEC scheme, a sync insertion unit inserting a sync into the encoded signal, a hidden pilot insertion unit inserting a hidden pilot into the sync-inserted signal, a pilot insertion unit inserting a pilot tone into the hidden-pilot-inserted signal, a pulse shaping filter pulse-shaping the pilot-tone-inserted signal with a certain roll-off factor, and a RF unit transmitting the pulse-shaped signal through a transmission channel band. Performances of equalization and synchronization acquirement can be enhanced in multipath conditions by utilizing the transmission system containing the hidden pilot.
