摘要：
A wireless device incorporates decentralized spectrum management to dynamically control a power level for each channel in a transmission spectrum. The decentralized spectrum management uses a common reference signal received from a TV station to select a channel and coordinate the transmitter power to mitigate interference. The decentralized spectrum management ensures that the propagation loss between the desired and interfering transmitters exceeds a desired power ratio in order to facilitate frequency reuse on a non-interfering basis.
