Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings.

[0039] refer to Figure 1 ~ Figure 3 , a spectrum pricing method based on user preference characteristics in a cognitive radio network, including the following methods:

[0040] 1), under equal bandwidth conditions, the channel quality with high-quality spectrum can be expressed as C h , the low-quality channel is C l , then C h >C l >0. Parameter C i refers to the channel capacity, which can be expressed as

[0041] C i = B log 2 ( 1 + ρ w I s i ) - - - ( 1 )

[0042] where B i...

Abstract

The invention provides a frequency spectrum pricing method based on user preference features in a cognitive radio network. Frequency spectrum pricing is carried out based on a Hotelling game model according to the quality of idle frequency spectrums, a frequency spectrum pricing system model is established at first, the idle frequency spectrums with different quality form a frequency spectrum pool and are divided into aequilate channels to be uniformly sold, and a cognitive user selects an appropriate channel in the frequency spectrum pool according to the demand per se and the frequency spectrum use preferences for purchase and use. The preference demand of the cognitive user is mainly affected by the quality of the frequency spectrums and the market forecast, and the quality of the frequency spectrums is mainly determined by the suffered interference. In the process, a dynamic game process is formed between a main system and a secondary user. Modeling analysis is carried out on the dynamic game process through the Hotelling model, and a reasonable frequency spectrum pricing result is obtained.

Description

technical field [0001] The invention relates to a spectrum pricing method based on spectrum quality division of an authorized system and cognitive user preference selection in a cognitive radio network, and belongs to the technical category of link layer resource allocation in the cognitive radio network. Background technique [0002] In cognitive radio networks, in order to make full use of spectrum resources and realize good spectrum resource sharing between licensed users and cognitive users, a lot of research work has been carried out one after another. Among them, dynamic spectrum access and allocation is the central issue of cognitive radio systems. In the underlay access mode of the dynamic spectrum access process, the cognitive user's transmission will be allowed without causing interference to the primary user. In an overlay visit, the cognitive user will occupy the spectrum of the primary user until he detects the reappearance of the primary user. In order to all...
