Patent ID: 8467482

Claim:
A method for identifying a transmitter in a digital broadcasting system, the method comprising: receiving a broadcast signal in which a TxID sequence for identification of a transmitter is embedded; correlating the received broadcast signal with a plurality of elementary code sequences of a pseudo-random sequence sequentially, wherein the pseudo-random sequence comprises a Kasami sequence; identifying the transmitter by using the correlation results; and wherein the Kasami sequence is generated using a first elementary code sequence (u), a second elementary code sequence (C(u″)) and a third elementary code sequence (S(u′)), and said correlating the received broadcast signal with a plurality of elementary code sequences of a pseudo-random sequence comprises: multiplying the received broadcast signal by an antipodal sequence of the first elementary code sequence; and filtering a result of the multiplication by a matched filter corresponding to the second elementary code sequence and filtering the filtering result through another matched filter corresponding to the third elementary code sequence.
