Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings.

[0042] refer to Figure 1 to Figure 7 , a spectrum pricing method based on the normal preference distribution of secondary users, including the following steps:

[0043] The first step, first, consider the utility function obtained by the secondary user after purchasing the authorized channel

[0044]

[0045] where s represents the channel quality, θ represents the channel selection preference of the secondary user and θ∈[θ L ,θ H ], p represents the channel price;

[0046] Let θ 0 Represents the preference parameter when cognitive users have no difference in demand for high-quality channels and low-quality channels, that is, when the user's preference parameter θ=θ 0 When , the secondary users gain the same utility, which can be obtained where p 1 and p 2 denote the channel prices of high-quality channel H and low-quality channel L respectively, s 1 and ...

Abstract

The invention discloses a spectrum pricing method based on secondary user normal preference distribution. Spectrums are priced through application of a Hotelling game model according to quality levels of idle spectrums. A spectrum pricing system model is established, and the idle spectrums of different quality levels form a spectrum pool and are divided into channels with equal widths for uniform sell. Secondary users select suitable channels for purchase and use from the spectrum pool according to own demands and spectrum use preferences. The preference demands of the secondary users are manly influenced by the spectrum quality and market estimation and are characterized by normal distribution. According to the method, the influences of different tendencies of a master system for the spectrums and economic benefits on spectrum pricing are analyzed. In the process, a dynamic game process between the master system and the secondary users is formed, the game process is modeled and analyzed through the Hotelling game model, and nash equilibrium is obtained.

Description

technical field [0001] The invention relates to the spectrum pricing game problem when secondary users choose different quality channels and their preference parameters are normally distributed, including the establishment of a wireless channel allocation model and the application of statistical theory in spectrum pricing, and belongs to the field of wireless communication technology Spectrum pricing method. Background technique [0002] With the continuous development of wireless communication technology and the establishment of future 5G communication standards, high-quality spectrum resources are increasingly scarce, which has become one of the bottlenecks restricting the development of wireless communication. Under such a background, the cognitive radio technology based on dynamic spectrum intervention has attracted more and more attention from the academic and engineering circles, and various new network technologies have begun to integrate dynamic detection spectrum an...
