Research On Performance Of Links In Cellular Network Based On Stochastic Geometry

With the rapid development of today's society,information and communication technology will surely become the key to the informatization of human society;at the same time,the rapid growth of wireless mobile communication services makes the role of information and communication systems become crucial.As the future information infrastructure,it has created the rapid rise of new fields such as the Internet of Everything and artificial intelligence.It is also the promotion and evolution of the first-generation mobile communication(1G)to commercial fifth-generation mobile communication(5G)technology by 2020.The continuous development of China's information industry,the number of mobile users and the increasing demand of users,the deployment of base stations is facing great challenges;the deployment of cellular network models in current mobile communications is also facing a more severe test;in large Occasions and better user experience in ultra-dense areas Bringing ultra-high performance experience to wireless networks also faces network deployment issues.In the decades of cellular mobile communications development,cellular network deployments brought about by user needs and different geographic environments have become a hot research direction;traditional Wiener models(regular hexagons)commonly used in network models are deployed with regular geometric figures,Cellular)can no longer accurately analyze complex cellular networks where multiple communication modes exist.Therefore,using convenient and accurate models to study current and future wireless cellular networks has become an important hot research.Firstly,this paper analyzes several related point processes in the random geometric model and its application in the field of wireless communication.After summarizing the characteristics of various models and comparing it with the traditional cellular network model,a cellular network chain based on the random geometric model is proposed.The significance of road research and the topology model of cellular networks.Secondly,this paper studies the performance of the uplink and downlink of the wireless cellular network.First establish the respective link network model,channel model and uplink and downlink interference model based on random geometric theory,and then derive their respective performance parameter formulas,and then simulate and analyze their respective cellular network link performance;such as coverage probability,frequency reuse,system Capacity,transmission rate,etc.Finally,in order to solve the problem of link multiplexing in cellular network systems,D2 D communication technology is introduced to ensure communication quality;and acommunication access scheme based on a random geometric model between users and base stations and between users is proposed to improve the reliability of user communications Performance,spectrum utilization and coverage.
