On the Injection-Level Optimization for Digital Television Transmitter Identification Systems Using Kasami Sequences

The transmitter identification of Digital TeleVision (DTV) systems becomes crucial now-a-days. Transmitter IDentification (TxID, or transmitter fingerprinting) technique is used to detect, diagnose and classify the operating status of any radio transmitter of interest. The TxID system is specified in Advanced Television System Committee (ATSC) A/110 standard where pseudo random sequences are proposed to be embedded into the DTV signals before transmission. Thus, the transmitter identification can be realized by invoking the cross-correlation functions between the received signal and the possible candidates of the pseudo random sequences.
