A statistical method for dynamic spectrum occupancy measurement

Abstract

A statistical method for dynamic spectrum occupancy measurement. The implementation steps are as follows: 1) with the sampling step f3, performing M (img file= '998175DEST_PATH_IMAGE001. TIF' wi= '19' he= '20'/) for monitoring frequency band (img file= '991539DEST_PATH_IMAGE 002. TIF 'wi=' 19 'he=' 19 '/) sub-spectrum monitor sampling, The returned sample values are column vector snapshots (img file= '683552DEST_PATH_IMAGE003. TIF' wi= '139' he= '26'/); 2) The receiver interference tolerance is (img file= '420563DEST_PATH_IMAGE004. TIF' wi= '26' he= '19'/). For frequency points (img file= '881632DEST_PATH_IMAGE005. TIF' wi= '21' he= '23'/), the field strength (img file= '311476DEST_PATH_IMAGE006. TI F 'wi=' 24 'he=' 24 '/) to compare and determine that interference tolerance value (img file =' 553102DEST_PATH_IMAGE004. TIF 'wi=' 26 'he=' 19 '/), Take (img file= '765908DEST_PATH_IMAGE007. TIF' wi= '47' he= '24'/), If (img file= '409379DEST_PATH_IMAGE008. TIF' wi= '63' he= '24'/), then(img file= '183694DEST_PATH_IMAGE009. TIF' wi= '44' he= '22'/); 3) sample snapshots were divide into (img file = '912615DEST_PATH_IMAGE010. TIF' wi= '17' he= '18'/) groups, Data matrices (img file= '991430DEST_PATH_IMAGE010. TIF' wi= '17' he= '18'/) were obtained (img file= '427090DEST_PATH_IMAGE011. TI F 'wi=' 23 'he=' 20 '/), Select near (img file= '198737DEST_PATH_IMAGE005. TIF' wi= '21' he= '23'/) (img file= '87059DEST_PATH_IMAGE012. TIF' w i= '33' he= '19'/), is a (img file= '218832DEST_PATH_IMAGE010. TIF' wi= '17' he= '18'/) data matrix (img file= '571315DEST_PATH_IMAGE013. TIF 'wi=' 22'he=' 25 '/); 4) Dynamically set the threshold level of the frequency point (img file= '451547DEST_PATH_IMAGE005. TIF' wi= '21' he= '23'/) (img file= '889481DEST_PATH_IMAGE 014. TIF 'wi=' 35 'he=' 26'/) and determine possession, take (img file=' 636331DEST_PATH_IMAGE015. TIF 'wi=' 50 'he=' 23 '/); If (img file= '108901DEST_PATH_IMAGE016. TIF' wi= '65' he= '26'/), then (img file= '160034DEST_PATH_IMAGE017. TIF' wi= '46' he= '26'/); (img file= '85264DEST_PATH_IMAGE018. TIF' wi= '20' he= '25'/) is (img file= '745790DEST_PATH_IMAGE005. TIF' wi= ' 21 'he=' 23 '/) correspond to that field strengthvalues in the data matrix (img file =' 807287DEST_PATH_IMAGE013. TIF 'wi=' 22 'he=' 25 '/); 5) Statistical spectrum occupancy (img file= '91638DEST_PATH_IMAGE005. TIF' wi= '21' he= '23'/) (img file= '441848DEST_PATH_IMAGE019. T IF 'wi=' 140 'he=' 37 '/). This method realizes the measurement and statistics of dynamic spectrum occupancy, reduces the monitoring time, improves the calculation precision, and can effectively reflect the occupancy of different frequency bands in real time.

Description

technical field [0001] The invention relates to a method for estimating spectrum occupancy, in particular to a measurement and statistics method for calculating dynamic spectrum occupancy based on field strength data fed back by spectrum monitoring equipment. Background technique [0002] Spectrum occupancy is a very important parameter in radio monitoring. It reflects the use of local spectrum resources, and provides a powerful tool for spectrum occupancy analysis, frequency allocation and assignment, and timely discovery of unknown and illegal signals, which in turn provides a powerful tool for the entire Spectrum management provides effective guidance. At present, each radio monitoring is to carry out the spectrum monitoring task of a certain frequency band in accordance with the relevant provisions of the "Ultrashort Wave Frequency Band Occupancy Test Technical Specifications (Trial)". First, each monitoring time is required to be no less than 24 hours. The obtained spe...
