    摘要： A wireless microphone system broadcasts a pilot tone at the designated ATSC pilot position in the TV Band channel being used by the wireless microphone system. The pilot tone is a readily detectable waveform transmitted in the ATSC pilot position. The pilot tone can be generated by any one of: a standalone pilot tone generator; a pilot tone generator incorporated into a wireless microphone receiver; or, a pilot tone generator incorporated into a wireless microphone.

    摘要： A television band device has DTV pilot signal detection logic that generates DTV pilot signal detection decisions associated with a monitored television channel. A wireless microphone detection logic generates wireless microphone detection decisions associated with the monitored television channel. A sensing manager receives DTV pilot signal detection decisions and the wireless microphone detection decisions and analyzes at least one the respective decisions to determine whether the monitored television channel is available white space.

    摘要： This invention discloses directional antenna systems, antenna combining and transmission antenna selection mechanism for wireless communication terminals such mobile handsets, mobile embedded laptops, mobile CPEs (Customer premises equipment), nomadic wireless CPEs, fixed wireless terminals and etc. The disclosed systems and methods only require analog circuitry and compass readings therefore are easy to implement and well fit into the current wireless terminals architectures. The inventive systems and methods resolve the problem that a directional antenna may not receive properly when user turn around and the antenna direction is deviated from transmitter; the inventive systems and methods further reduce the interference caused by omni antenna systems by selecting a directional antenna for transmit.

    摘要： A radio frequency front end for a television band receiver and spectrum sensor includes a first plurality of adaptive matching networks connected to a signal summer that combines signals received by the first plurality of antennas respectively connected to the first plurality of adaptive matching networks and outputs a combined signal to each of a second plurality of downconverter/tuners. The downconverter/tuners are respectively or collectively connected to an analog to digital converter that converts output of the second plurality of downconverter/tuners into at least one digital signal that is output to the television band receiver and spectrum sensor.
