Embodiment Construction
[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0046] Based on the status quo of spectrum allocation in the 230MHz industry, the candidate spectrum sharing scheme must be compatible with various narrowband systems operating on the existing network, allowing discrete 25kHz frequency points to be available for a long time; it must also take into account the business development needs of the future broadband sensing system and combine multiple 25kHz frequency points , support large bandwidth services such as v...

The invention discloses a method for sensing spectra on the basis of group spectrum pools. The method includes judging whether the numbers of frequency points of a sensing system in frequency bands of preset bandwidths change or not; acquiring the numbers N of the frequency points if the numbers of the frequency points of the sensing system in the frequency bands of the preset bandwidths do not change; sequentially arraying power values of all the frequency points in the frequency bands of the preset bandwidths from large to small and acquiring accumulated power corresponding to the first N power values; judging whether spectrum resources in the frequency bands of the preset bandwidths are idle or not according to the accumulated power. The invention further discloses the system for sensing the spectra on the basis of the group spectrum pools. The system comprises a frequency point number judging unit, a frequency point number acquiring unit, a power computing unit and a first judging unit. The method and the system have the advantages that the busy-idle degrees of the spectrum resources in the frequency bands of the preset bandwidths can be judged, accordingly, the utilization rate of the spectrum resources can be effectively increased, and requirements of users in industries can be met.
Description
technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a spectrum sensing method and system based on grouped spectrum pools. Background technique [0002] At present, the 223-235MHz frequency band is planned for telemetry, remote control, data transmission and other services, and is mainly used in key industries such as energy, military, meteorology, earthquake, construction, water conservancy, geological mining, and light industry. This frequency band uses a fixed allocation method for spectrum management, the frequency bandwidth is 25kHz, and the frequency points of various industries are in a state of discrete distribution. [0003] With the deep integration of industrialization and informatization, users in various industries such as electric power and petroleum have put forward more and more demands on the bandwidth of wireless private networks. At present, my country mainly adopts a fixed allocation meth...
