Optimizing decision method and system for capacity of VHF communication radio station spectrum pool

Abstract

The invention relates to an optimizing decision method and system for the capacity of a VHF communication radio station spectrum pool. After spectrum sensing is carried out on a VHF communication radio station to acquire the channel quality according to the total channel number, the work channel number K, the channel quality time varying probability pE, the channel quality time varying range s andchannel selection accuracy requirement Pcover parameters input by a user, a closed mode tagmeme covering probability calculating method is adopted, and the optimal value B of the capacity of the spectrum pool is calculated and determined. Therefore, a communication radio station can select B channels from sensed channels from high to low as the spectrum pool according to the optimal value, the subsequent channels selected from the channels are allowed to carry out data communication, and after the channels in the spectrum pool are used up, the time varying parameters are dynamically adjusted.According to the method, the optimal value of the capacity of the spectrum pool can be determined after the channel quality is acquired through spectrum sensing, a radio station user reduces the number of times of frequency spectrum migration failing to the maximum degree, the frequency spectrum utilization rate is effectively increased, and the requirement for channel selection accuracy put forward by the user is met.

Description

technical field [0001] The invention relates to a decision-making method for optimizing the capacity of a frequency spectrum pool of a VHF communication station, which belongs to the intersection field of radio technology and big data, and specifically relates to a decision-making method for optimizing the capacity of a spectrum pool of a cognitive radio VHF communication station. Background technique [0002] The spectrum pool refers to a channel set maintained by the communication station system, and each channel in the set is used as a spectrum resource for the communication station to choose and use during the communication process. Spectrum pool capacity refers to the size of the spectrum pool. If the spectrum pool is too large, spectrum switching may fail due to the time-varying characteristics of spectrum quality, reducing communication efficiency. If the spectrum pool is too small, some channels with better spectrum quality may be missed, which wastes spectrum resourc...
