US 2010/0150015 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 N number of antennae, N number of demodulators, N number of known sequence detectors, and an equalizer. The N number of antennae each receives a broadcast signal including mobile service data and known data sequences. The N number of demodulators demodulates the broadcast signal received by the corresponding antenna. The N number of known sequence detectors detects known data sequences from the broadcast signal received by the corresponding antenna. The equalizer estimates a channel impulse response (CIR) of a broadcast signal received and demodulated by each antenna based upon each known data sequence detected by the N number of known sequence detectors, calculates an equalization coefficient of the broadcast signal received and demodulated by each antenna based upon at least one of the estimated CIRs, so as to compensate channel distortion of the broadcast signal received and demodulated by each antenna, and combines at least one or more distortion-compensated broadcast signal, thereby finally outputting the combined signal.

Dependent claims

A receiving system, comprising:

N number of antennae each receiving a broadcast signal including mobile service data and known data sequences (wherein N is an integer greater than or equal to ‘2’);
N number of demodulators corresponding to each of the N number of antennae and demodulating the broadcast signal received by the corresponding antenna;
N number of known sequence detectors corresponding to each of the N number of antennae and detecting known data sequences from the broadcast signal received by the corresponding antenna;
an equalizer estimating a channel impulse response (CIR) of the broadcast signal received and demodulated by each antenna based upon each known data sequence detected by the N number of known sequence detectors, calculating an equalization coefficient of the broadcast signal received and demodulated by each antenna based upon at least one of the estimated CIR, compensating channel distortion of the broadcast signal received and demodulated by each antenna, and combining at least one or more distortion-compensated broadcast signal, thereby finally outputting the combined signal;
and
a decoder block-decoding mobile service data contained in the distortion-compensated broadcast signal.
