摘要 UWB室内小尺度参考信道模型存在局限性.在考虑信道时变性和多普勒效应的情况下,探测分析UWB室内信道瞬时与空间的变化特性.针对信道的平均功率时延剖面特性,采用裁减算法给出UWB室内时空信道离散部分和弥散部分数学建模的方法、参数和模型.时空信道模型的初步仿真结果表明,该模型能较好地吻合信道探测特性和已有的研究结果. UWB indoor small-scale channel reference model has some disadvantages.Considering the time-variant and Doppler effects of channel,further measurement and analysis of UWB indoor characteristics are carried out.According to APDP of channel,tailored algorithm is used to generate the arrival times and amplitudes of individual echoes and their clusters.The model parameters,modeling means of new UWB indoor small-scale time-space channel is proposed.The simulation results of the channel model accord with the measured channel and other study results better.
