METHOD AND APPARATUS FOR ATSC SIGNAL PROCESSING

摘要

Embodiment methods and apparatus enable ATSC receiver devices to receive and process ATSC-M/H training sequences in order to improve the reception and decoding of an ATSC service. A processor within the ATSC receiver device may be configured to receive training sequences 1 and 2 of the ATSC-M/H signal. In an embodiment, the ATSC-M/H training sequence 2 may be received by correlating symbols of the two halves of the training sequence 2. If the result of correlating the symbols is greater than or equal to a threshold, the ATSC-M/H training sequence 2 may be received by the ATSC receiver and a counter for the training sequence 1 may start. The ATSC receiver may correlate two consecutive training sequences 1 to perform fine residual frequency error estimation.
