A spectrum allocation algorithm with fast response to interference

Because spectrum resources are scarce and not shareable, a large number of working electronic devices in the same area are prone to interference. When electronic device is interfered, how to quickly eliminate the interference is important. To solve the problem of spectrum resource allocation and interference elimination between electronic devices, this paper proposes a spectrum allocation algorithm that can quickly respond to interference. The algorithm comprehensively considers electromagnetic environment restrictions, priority of electronic devices, potential interference between electronic devices, the number of frequency points required by devices and other restrictions. When interference occurs, the algorithm can respond quickly and provide a frequency-using strategy to eliminate the interference, which provides guarantee and support for the normal operation of the device.
