Apparatus and Method for Sensing an ATSC Signal in Low Signal-To-Noise Ratio |
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, wherein the ATSC signal detector includes a filter matched to a PN511 sequence of an ATSC signal for filtering a received signal on one of the number of channels for providing a filtered signal for use in determining if the received signal is an ATSC signal. The ATSC signal detector can be a coherent or a non-coherent ATSC signal detector.
