US 2010/0135375 A1 · TRANSMITTING/RECEIVING SYSTEM AND METHOD OF PROCESSING BROADCAST SIGNAL IN TRANSMITTING/RECEIVING SYSTEM

Abstract

A receiving system and a method of processing broadcast signal are disclosed herein. The receiving system includes a signal receiving unit, a detector, and a channel equalizer. The signal receiving unit receives a broadcast signal including mobile service data and a data group including N number of training sequences. The detector detects N number of training sequences from the broadcast signal (wherein N≧5), wherein the detected N number of training sequences are received during N number of training sections. And, the equalizer estimates a channel impulse response (CIR) of N number of training sections, based upon the detected N number of training sequences, applies the channel impulse response estimated in M number of training sections (wherein N≧M) to a cubic spline interpolation function, so as to generate a channel impulse response of (N−1) number of mobile service data sections located between the N number of training sections, thereby performing channel-equalization on the mobile service data of the corresponding mobile service data section.
