Based On LTE Wireless Network Construction Capacity Optimization Technology Research

The main idea of LTE network optimization is to use various optimization methods to achieve dynamic balance in coverage and capacity,so that the quality of the network can be greatly improved to ensure the user?s perception.This article first introduced the structure of the LTE network,elaborated the architecture of both the E-UTRAN access network and the EPC core network,and explained their functions.The listed the three core technologies of LTE network:Orthogonal Frequency Division Multiplexing(OFDM),Multiple Input Multiple Output(MIMO),and Self Organizing Networks(SON).Next,this paper takes the actual situation of Guizhou Polytechnic of Construction network as anexample to carry out capacity optimization resear ch,and introduces a new type of frequency reuse structure-overlapping fractional frequency reuse structure.Based on this structure,a mixed service is proposed.LTE network optimization algorithm.This paper introduces the principle and specific flow of the algorithm in detail,and uses Matlab to simulate it,and compares it with other traditional algorithms,thus verifying that not only can the capacity of the LTE system be increased,but also the mutual suppression between cells can be effectively suppressed.Interference and guarantee user quality.Finally,an improved hybrid service LTE network algorithm is proposed for the disadvantages of overlapping fractional frequency reuse structures.Through simulation experiments,it not only can increase the capacity of the LTE system,but also can more effectively prevent interference and improve user quality and have better performance.
