LTE系统级仿真+文献综述

摘要随着“移动通信宽带化”发展趋势越来越明显，为了解决第二代和第三代移动通信技术不满足传输速率等要求的问题，3GPP组织启动了LTE项目。LTE改变空中接口和网络结构，并采用协作多点传输、频谱聚合、多载波调制等先进技术。由于功率和带宽受到限制，在实际部署时需要考虑LTE系统的配置和网络规划问题，从而尽可能获得高的业务速率和用户服务质量。因此需要通过系统级仿真评估对系统进行合理规划来解决这一问题。28226

Title          STUDY ON LTE SYSTEM-LEVEL SIMULATION
Abstract
With the the trend of broadband mobile communications becoming more and more obvious,in order to solve the problem that the second generation and the third generation cannot meet the requirements of the transmission rate and others,3GPP launched the LTE Project.Air interface and network structure have been changed and a series of advanced technologies such as cooperative multi-point,spectrum aggregation,multi-carrier modulation have also been applied .Due to the limited power and bandwidth,how to deploy and configure the system better should be considered to receive business rate and service quality as high as possible.Therefore,system-level simulation is used to plan the system reasonably to solve the problem.
This graduation design is based on the OT-GMC simulation platform and has been modified into the platform of LTE.Firstly,we study the structure of the LTE system,the technology of the physical layer and network function.Next,We research the link level simulation and system level simulation.This paper presents a quasi static simulation scheme for LTE simulation and design the interface between link level simulation and system level simulation.
This paper re-determine the wireless channel module,scheduling algorithm,HARQ and
other modules and derive the calculation method of SINR.We build the platform using MATLAB.We measure performance benchmarks.Then we compare the simulation results of the relevant indicators anf analyze the impact on system performance.
