Abstract
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, wherein the ATSC signal detector is a threshold-based detector and detects an ATSC signal as a function of at least one threshold, and wherein the ATSC signal detector is responsive to at least one of a carrier tracking loop lock signal, a symbol timing recovery lock signal and a synchronization (sync) lock signal.
