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 a fourth generation mobile communication technology, International Mobile Telecom Advanced (IMT-Advanced) can provide higher data than the third generation mobile communication system (IMT-2000, International Mobile Telecom System-200) Rate and better user experience. In order to adapt to the new wireless propagation characteristics, the International Telecommunication Union (ITU) proposed relevant test environments and evaluation scenarios, which are of great significance for carrying out relevant technical research, system evaluation and testing. The establishment of IMT-Advanced channel model is more complete and accurate than the earlier models, and is suitable for analyzing and studying the radio propagation characteristics in different scenarios.
