摘要： A Wireless Regional Area Network (WRAN) receiver comprises a transceiver for communicating with a wireless network over one of a number of channels, and an Advanced Television Systems Committee (ATSC) signal detector for use in forming a supported channel list comprising those ones of the number of channels upon which an ATSC signal was not detected. The ATSC signal detector computes at least one cyclostationary feature of a received signal for determining if the received signal is an incumbent ATSC broadcast signal.

摘要： An Advanced Television Systems Committee Digital Television (ATSC DTV) transmitter transmits a digital multiplex that includes a legacy DTV channel and a mobile DTV channel. The mobile DTV channel is conveyed in mobile packets that comprise mobile data and additional mobile training information. A mobile packet comprises 207 bytes wherein 2 bytes are header information, 20 bytes are Reed-Solomon (RS) parity information and 185 bytes convey mobile data and mobile training information. The mobile training information is inserted into mobile packets such that the additional training information appears in contiguous positions after convolutional interleaving.

摘要： A signal comprises a sequence of fields, each field having a synchronization portion and a data portion, a transmitter inserts a pseudonoise (PN) sequence into the synchronization portion of a field for use in identifying a presence of mobile data in the data portion of that field; and transmits the signal. In complementary fashion, a receiver receives the signal and upon detecting the PN sequence in the synchronization portion of the received signal determines whether or not mobile data is in the data portion of that field of the received signal.

摘要： A preamble identifier flag in a reserved portion of a data field synchronization segment in a digital television (DTV) data field identifies the presence of preamble training data in a forward error correction (FEC) encoded portion of the DTV data field. The data field synchronization segment is not FEC encoded, thereby allowing detection of the preamble identifier flag without FEC decoding. The detection at a receiver of the preamble identifier flag in a DTV data field allows receiver elements, such as an equalizer and a FEC decoder, to more readily obtain and utilize the preamble training data, thereby enhancing reception and/or simplifying receiver design.
