Method and system for optimal selection of channel measurement set of VHF communication station

Abstract

The invention relates to a VHF communication radio station channel measurement set optimization selection method and system. According to five parameters such as a channel total quantity n, a workingchannel quantity K, channel bottom noise change probability pE, a channel bottom noise change range s and an accuracy requirement Pcover selected by a channel measurement set input by users, an ordercoverage probability calculation method can be adopted to determine the optimal value of the channel measurement set through calculation before a VHF communication radio station begins to detect channel quality, and therefore, the communication radio station can select the best channel measurement set to perform further channel quality detection from results obtained by an energy detection methodaccording to the optimal value. The optimal value of the channel measurement set can be determined in advance before the channel detection, and thus, channel measurement times and energy consumption can be maximumly reduced, radio station position exposure risk can be lowered, and channel measurement set selection accuracy requirements provided by users can be met.

Description

technical field

[0001] The invention belongs to the intersection field of cognitive radio technology and big data, and in particular relates to a method and system for optimizing and selecting a channel measurement set of a cognitive radio VHF communication station. Background technique

[0002] Channel measurement refers to the use of two radio stations. After the radio stations are synchronized, a sending station sends a message on a certain channel to a receiving station. The receiving station measures the signal-to-noise ratio of the channel during the process of receiving the message, and repeats In this process, a total of B channels are subjected to the same test, and finally K channels with the best quality and the highest SNR are determined as working channels. Since channel measurement consumes more energy, it is necessary to use traditional energy detection methods to pre-select B channels with lower noise floor from a spectrum space containing n channels.
