Abstract

The invention discloses a bidding optimization method of frequency spectrum auction of fractional order frequency reuse. The method comprises the following steps that 1) a frequency spectrum auction model of fractional order frequency reuse is established, a seller submits information of to-be-rent frequency range of himself/herself to an auction intermediary, and the auction intermediary gathers and arranges frequency spectrum resources to be auctioned and then put the resources in a frequency spectrum pool so that buyers with frequency spectrum demands can bid for the frequency spectrum resources; S2) a target function in which income of a main client is maximized is established, an interference price factor is optimized, and optimization is broadcast to secondary users in auction; S3) precoding and power distribution design are carried out in a combined manner by utilizing the optimized interference cost factor omegak* in a scene of fractional order frequency reuse , and the secondary users are divided into cell center secondary users and cell edge secondary uses, and analysis is carried out on the cell center secondary users and the cell edge secondary uses; and S4) bidding of the secondary users in auction is optimized. According to the method, the method is easy to realize and convenient to expand and approaches practical applications more, and a frequency spectrum auction manner has high distribution efficiency and better interference inhibition effect.

Description

technical field [0001] The invention relates to the field of cognitive radio technology, in particular to a spectrum auction bid optimization method for fractional frequency reuse. Background technique [0002] With the rapid development of science and technology and the continuous improvement of people's communication requirements, wireless spectrum resources are becoming increasingly scarce. At the same time, the use of existing frequency bands is unreasonable, spectrum congestion and idle spectrum coexist, and there must be mutual interference in the process of information transmission. , the communication quality needs to be improved urgently. Therefore, how to improve the allocation efficiency and utilization efficiency of existing spectrum resources as much as possible, and effectively suppress the mutual interference between users has been a research hotspot for a long time. [0003] Fractional frequency reuse is an effective frequency reuse technology. It divides th...
