摘要：
A Wireless Regional Area Network (WRAN) receiver includes a tuner for tuning to one of a number of channels, and a broadcast ATSC (Advanced Television Systems Committee) signal detector. The tuner is calibrated as a function of a received ATSC signal. The broadcast ATSC signal detector can be a coherent or a non-coherent ATSC signal detector.
