摘要： An implementation provides a transmitter that separates sequential portions of data in a first set of data by time intervals allowing a power saving mode (1005). The transmitter transmits the sequential portions of data separated by respective time intervals having lengths configured to allow a receiver to enter and exit a power saving mode between receiving sequentially transmitted portions of data from the first set of data (1010). The transmitter separates sequential portions of data in a second set by time intervals that are not of sufficient length to allow a receiver to enter and exit a power saving mode during the time intervals (1015). The second set of data is then transmitted (1020).

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 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 comprises a matched filter that matches to at least a modulated version of an ATSC field sync signal for detecting the presence of an incumbent ATSC broadcast signal.
