无线信道模型研究与展望(一)

Research and Perspective of Wireless Channel Models(1)

随着信息技术的迅猛发展,无线通信成为越来越重要的通信方式之一,从而对信道提出了更严格的要求。回顾并综述了常用的典型无线信道模型,对各种信道的特点和适应场景进行了详细的分析、对比与总结,为实际应用中根据不同环境选择合适的信道模型提供了参考。最后,对其中一些信道模型的优化方向给出了建议,并对信道模型的应用前景进行了概括与展望。

With the rapid development of information technology,wireless mobile communication has become one of the most important means of communication,and there are more stringent requirements on the channel.Several typical wireless channel model which are frequently-used are reviewed,and the background of these typical and frequently-used channel models is introduced.Several typical and common characteristics of the channel models are investigated,analyzed,compared and summarized.It provids theoretical reference for selecting the appropriate channel model in practices.At last,it gives suggestion to optimize the direction of some channel models,and some applications of channel model are generalized and prospected.
