APPARATUS AND METHOD FOR MODULATING OF ON-CHANNEL REPEATER
摘要
Provided is a modulating apparatus and method of an on-channel repeater. An object of the present invention is to provide a modulating apparatus of an o n- channel repeater for reducing time delay by configuring and up-sampling a baseband signal, filtering the up-sampled baseband signal with an Equi-Rippl e (ER) filter or in a window method, and converting the filtered baseband sign al into an RF signal. The modulating apparatus includes: a baseband signal configuring unit for configuring a baseband. signal by combining an input field and a segment sync signal; a pilot adding unit for adding a pilot sign al to the baseband signal; a filtering unit for filtering the baseband signal with the pilot signal; and an RF up-converting unit for up-converting the filtered signal into an RF signal. The present invention is used to form an on- channel repeating network in a transmitting system including a digital TV broadcasting system.
