摘要

本文描述了一种用于宽带电信业务ADSL-I部署的射频干扰(RFI)分析的自动化系统。该系统包括工程程序和美国所有授权发射机的数据库。，频率范围在100 khz至500 khz之间。首先计算任意指定位置的干扰信号电平。然后进行分析以预测客户处所的网络接口上的耦合电压。计算总噪声谱(来自该电压)，并与可靠性能的最大容忍噪声进行比较。噪音频谱超过阈值的区域被定义为关键区域，并在地图上以阴影区域表示。未来，该系统将升级，以分析ADSL-III和其他宽带服务在更高频率范围内的RFI研究，并将包括在感兴趣的频率上绘制场等高线的更多功能。

An automated system for RFI analysis for deployment of ASDL-I

This paper describes an automated system to perform radio frequency interference (RFI) analysis for the deployment of a broadband telecommunication services, ADSL-I. The system include engineering programs and a database of all the licensed transmitters in the US., within the 100-kHz to 500-kHz frequency range. Interfering signal levels at any specified location are first calculated. Analysis is then performed to predict the coupled voltage at the network interface of the customer premises. The total noise spectrum (from this voltage) is calculated and compared with the maximum tolerable noise for reliable performance. Areas where the noise spectrum exceeds the threshold value are defined as critical areas and indicated as shaded regions on a map. In future, the system will be upgraded to analyze RFI study at higher frequency ranges for ADSL-III and other broadband services and will include more capabilities for drawing field contours at frequencies of interest.<>
