TRACKING RADAR FREQUENCY ENABLING MORE CHANNELS

摘要

In an example embodiment, a channel that includes a plurality of sub-channels is sampled to detect pulses indicative of a presence of a radar signal. A frequency for the radar signal is determined. If the frequency of the radar signal maps to a selected subset of the plurality of sub-channels, the selected subset of the plurality of sub-channels are determined to be unavailable due to radar, while the remaining sub-channels remain available for use. The selected subset of the plurality of sub-channels determined to be unavailable due to radar may be selectively returned for use after the radar signal is no longer detected for a predetermined selected time period.

1. Logic encoded in a tangible, non-transitory computer readable medium for execution and when executed by a processor operable to:
select a wide band channel comprising a plurality of sub-channels; detect a primary user on the wide band channel; map the detected primary user to a first sub-channel of the plurality of sub-channels in accordance with a frequency of the primary user; and enable communication on a selected second sub-channel of the plurality of sub-channels that does not include the frequency of the primary user.
