中文摘要：
家庭宽带局域网是互联网的延伸，也是未来智能家居的信息技术基础。该文提出一种使用超宽带和高速宽带电力线技术构建家庭智能宽带局域网的新方案。然后根据宽带电力线传输特性与辐射特性，从电磁辐射与信号分析两方面研究宽带电力线通信系统与超宽带通信技术的共存性。通过对宽带电力线信号的仿真与现场测试，提出了宽带电力线的辐射计算模型，进一步研究超宽带信号在宽带电力线辐射场中的波形与误码率变化。结果表明在相应的条件下这两种宽带通信技术在室内环境中有着较好的网络共存性，为构建规范的家庭内部智能宽带局域网提供了相应的技术保障。
英文摘要：
The indoor broadband LAN （Local Area Network） is the extension of the Internet and is also the technique basement of the smart house in the future. This paper introduces one novel method to make up the indoor broadband network firstly with the BPL （Broadband Power Line） communication and the UWB （Ultra Wide Band） communication techniques, which make kinds of indoor equipments connected into the LAN. Then on the base of the transmission and radiation characters of the BPL, the coexistence of the BPL and the UWB is analyzed on two sides： the electromagnetic radiation and the signal analysis. After simulating the BPL signals and testing the radiation, the calculation model for BPL system is proposed to analyze the performance of the UWB BER （Bit Error Ratio） in the BPL radiation field. The result shows that two broadband communication techniques are suitable for coexistence, which supports a relevant technique basement of the normative indoor broadband LAN for the smart house.
