摘　　要：高速宽带电力线通信是实现家庭局域网的一种新颖的实用技术。由于技术自身特点,它所产生的电磁辐射改变了室内电磁环境,必然会对室内其他无线电业务产生影响。在分析高速宽带电力线通信的信道特性、网络阻抗特性与衰减特性基础上,建立电力线网络对外的辐射计算模型。通过计算机仿真计算得到室内空间的辐射场,并且由实验测量数据验证。在辐射模型的计算基础上,研究了高速电力线通信对室内无线通信系统的电磁干扰,为制订高速宽带电力线通信的技术标准奠定研究基础。The high speed BPL （broadband power line communication） is a novel and practicable technique for home LAN （local area network）. Because of its transmitting characters, the electromagnetic radiation emitted from the BPL influences the indoor electromagnetic environment, which would also affect the performance of others indoor wireless communication. Based on the analysis of channel character, network impedance and attenuation character of the BPL, a novel calculation model for the BPL radiation is constructed. The validity of the model is proved by com- puter simulation and test data. The interference of the high speed BPL to the indoor wireless communication is analyzed to stipulate for the standards of the high speed BPL in the future.
