With the development of wireless communication networks,the number of terminals is increasing,various terminals are innovating and the explosive growth of mobile bandwidth services has promoted the further study of wireless networks.Under such circumstances,through the base station intensive deployment,increase the communication small base station,balanced load and other means of research,users can bring a good user experience.In this thesis,the interference coordination between small base stations in ultra-dense networks is studied,and the network throughput reduces by reducing the interference by rational planning.Based on the research status of ultra-dense wireless network communication deployment,this thesis studies frequency-division multiplexing algorithm for inter-cell cooperation,interference clustering management of dense network.Firstly,a frequency division multiplexing algorithm based on inter-cell cooperation is proposed for the characteristics of base station-intensive deployment of ultra-dense networks.The algorithm increases the inter-cell cooperation on the basis of frequency division multiplexing to reduce the interference to make up the shortcomings of low frequency utilization in frequency division multiplexing and improve the efficiency of network control.The simulation results show that the algorithm can effectively improve the network resource utilization and system capacity.Secondly,the thesis studies the interference-clustering algorithm in the ultra-dense network,and proposes the power allocation algorithm based on the interference degree as the clustering basis,by clustering the base stations with the least interference among the networks.The algorithm combines the interference and clustering in the dense network.According to the degree of interference,the interference is divided into the same cluster.The base stations in the same cluster share the spectrum resources and cooperate to provide services for the users.Moreover,the clusters share the spectrum resources.Simulation results show that the proposed algorithm can reduce the interference and allocate the optimal power to increase the network throughput in dense deployment.In the end,a network deployment system based on LTE small base station is designed,and realizes the intelligent regulation of network resources through interference and coordination management.The system takes HD video transmission as an example and optimizes the base station selection with various resources in the network,which can satisfy the speed of the future network needs,the large amount of data and lower overhead requirements.The design and verification show that the system can fully utilize the wireless resources and realize the intelligent regulation of the network resources while satisfying the users' service requests.
