摘　　要：作为第四代移动通信技术,高级国际移动通信(IMT-Advanced,International Mobile Telecom Advanced)相比于第三代移动通信技术(IMT-2000,International Mobile Telecom System-200),能够提供更高的数据速率和更好的用户体验。为了适应新的无线传播特性,国际电信联盟(ITU,International Telecommunications Union)提出了相关的测试环境和评估场景,这对开展相关技术研究,系统评估和测试具有重要的意义。IMT-Advanced信道模型的建立,相比与早期的模型更加完善,也更加准确,适于在不同场景下对无线传播特性进行分析和研究。As the fourth generation mobile communication technology,IMT-Advanced technology could provide higher data rate and better user experiences than IMT-2000.In order to match the new features of wireless transmission,ITU proposes the related test environment and evaluation scenarios,and this is of great significance for technical research,system evaluation and test.IMT-Advanced channel model is more complete and accurate,suitable for analysis and research of radio propagation characteristics in various scenarios.
