摘要
通用且随机的超宽带室内信道模型对物理层标准评价、系统设计和性能分析起重要作用。本文首先介绍了超宽带室内信道的典型特征,然后在信道探测的基础上详细描述了超宽带室内参考信道模型,并结合具体超宽带室内环境对信道模型参数进行仿真,将仿真结果与探测信道统计特性进行比较,分析了信道模型结构对系统设计和性能分析的影响,指出超宽带室内参考信道模型的局限性,最后得出进一步研究超宽带室内信道模型的必要性。
It＇s important for evaluating UWB physical layers protocol, system design and system performance analysis to establish a universal stochastic UWB indoor channel model. The typical characteristics of UWB indoor channel are first introduced. Then based on sounding channel, UWB reference channel model is studied. And the performance parameters of reference channel model are simulated. The simulation results are compared with sounding channel statistics parameters. It is analyzed that the structure of channel model has an important influence on system design and performance assessment. The disadvantages of UWB reference channel model are pointed out. At last further study on UWB indoor channel model is necessary.
