Spectral Allocation Algorithm Based On Auction Mechanism In CoMP System

With the rapid development of new generation of mobile communication technology,users' demand for wireless communication is increasing.How to improve the spectrum utilization of wireless communication system,and thus upgrade the system throughput of wireless communication services,has always been the urgent concern in the field of wireless communications focus.Based on the development demand for future wireless broadband high-speed data services,the Coordinated Multi-point(CoMP)system is widely considered to improve the throughput of the whole communication system by improving the communication quality of the users at the edge of the cell.Thus,CoMP is recognized as one of the most promising candidate technologies within future mobile communication development process.Although the introduction of CoMP system brings new vitality for spectrum resource allocation,the spectrum allocation method of inherent CoMP system is a static allocation method,which has poor flexibility in band division and low spectrum utilization of CoMP system.Due to its scarcity and non-reproducibility of spectrum resources,it is important to solve the problem of low spectral efficiency in CoMP system and develop the dynamic allocation schemes of limited spectrum resources.The above goals have important theoretical and practical significance.Due to the mature applications of auction theory and the low utilization rate of wireless spectrum resources in CoMP system,we study auction theory in order to solve the problem of low utilization of spectrum resources in CoMP system.This paper mainly focuses on the problem of low spectrum resource allocation in CoMP system,and utilizes the auction theory to allocate the spectrum resources in CoMP system.Based on the application scenario of CoMP system and the characteristics of auction theory,we propose two optimization algorithms to improve the spectrum utilization and overall throughput of the system.First,we analyzed the application scenarios of the wireless band within the CoMP system.Then,in order to finish the aims of improving the spectrum utilization and system throughput within the system,a dynamic multi-band multi-winner greedy algorithm based on auction mechanism is proposed in CoMP system.In addition,we propose a joint beamforming and power allocation algorithm based on auction mechanism,which is based on auction game theory and joint beamforming and power distribution technology.The algorithm is designed to improve the spectrum of CoMP system utilization and overallthroughput.Finally,from the simulation results,we can see that the two algorithms not only meet the needs of the system scene,but also enhance the system's bandwidth utilization and system throughput.For the optimization of spectrum resource algorithm in CoMP system,these research results of this paper have practical reference significance,and it can be used for reference in the optimization design of mobile network.
