Various terrestrial digital television broadcasting standards have been developed in the last two decades for both fixed residential and mobile receivers. Since personal mobile terminal integrated with multiple functionalities is becoming more popular, it is highly desirable to come up with a universal platform for mobile TV reception which can detect the system parameters of DTV signals automatically and adjust its receiving mechanism correspondingly. In this paper, the authors propose a progressive automatic method for parameter extraction of OFDM-based mobile broadcasting signals. Classification of ATSC and OFDM based DTV signals can be easily achieved with the unique pilot of ATSC signals.
