| 摘 要： | 研究了超宽带（UWB）无线通信系统抗WiMax系统的近场电磁干扰能力,为此,首先构建了包括UWB系统和WiMax近场电磁干扰等效的分析模型;其次,基于该分析模型研究了WiMax近场干扰对IEEE 802.15a UWB系统接收灵敏度的影响,得到了在给定场景和WiMax系统参数条件下,UWB系统接收灵敏度的回退量ΔS与其传输速率的关系曲线模型。该关系曲线模型对UWB＋WiMax双模系统共存设计具有重要的理论指导意义。

| Abstract: | In this paper,the ability of anti-near-field electromagnetic interference which came from WiMax system of UWB system is analyzed.For this,at first the wireless communication system of UWB and the equivalent analysis model of near-field electromagnetic interference are built.Then,based on wireless communication systems of UWB and the equivalent analysis model of near-field electromagnetic interference,it studied the impacts on the receiving sensitivity of UWB system because of the interference came from WiMax near-field,and obtained the relationship curves between the UWB system receiving sensitivity degradation ΔS and the UWB transmitting rates.The relationship curves model has important theoretical instruction significance in the design of UWB＋WiMax co-existence dual-mode system. |
