Spectrum Utilization Efficiency Evaluation Method of Radio System by using A Spectrum Overlay Sharing Technique

摘要

The invention DTV (Digital TV) system and the spectral overlay mode of cognitive radio system in the TV band When sharing a frequency, relates to a method for evaluating the frequency utilization efficiency by the frequency sharing technology effectively, using the respective frequency bands of the plurality of frequency bands and the first wireless system, the second to share the frequency band in the frequency utilization efficiency evaluation method in a wireless environment having a wireless system, (a) the design parameters for the first wireless system, the method for calculating the coverage with the coating chamber a design parameter of the second wireless system; And (b) a step of evaluating the frequency use efficiency per unit area using the calculated the thread coverage unit, the coverage of the coating chamber, each of the respective coverage of the first wireless system using a frequency band of each frequency the second is from the sum of the coverage of the radio system, each calculated by subtracting all the overlapping region overlapping frequency bands used by the band.
