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.

摘要： A method and system for detection of available a white space channel in an area of licensed transmitters includes a detector which utilizes the autocorrelation analysis of a channel in an frequency modulated (FM) band. Calculation of the autocorrelation excludes an initial set of correlation delay values such that large values of autocorrelation are removed. The remaining autocorrelation based on higher correlation delay values exposes the sinusoidal nature of an FM transmitter operating in the selected channel. White space becomes available to a user if no transmitter is detected using the autocorrelation detection method.

摘要： A method and apparatus for using 802.11 Wireless LANs in TV white space are provided that additionally allows coexistence with non-802.11 devices in the same spectrum space. The method and apparatus extend concepts used in traditional 802.11 applications in the MAC and PHY layers so that WLANs can function over TV white space channels. The method and apparatus also facilitates coexistence of non 802.11 devices and existence with other 802.11 applications by extending the Enhanced Distributed Channel Access mechanism used to provide quality of service. An OFDM system with fixed subcarrier spacing is suggested to accommodate spectrum characteristics (variable center frequency and channel bandwidth) of the TVWS.
