The conventional power-line communication (PLC) is a communication method which injects the communication signals between the lines of 100 volts, where the injection method is called the normal-mode injection. On the other hand, the proposed injection method was done between the 100V line and the earth, and called the phantom-mode injection. The injected phantom-mode signals were emitted from the 100V line to space. If many lines are wired in a closed space like a room, a weak electric-magnetic field will be filled, so that radio communications become possible. The communication performed in such a situation is called "a cable and radio fusion type PLC". In this research, a system of the fusion type PLC that was applied to achieve the highly accurate localization of an indoor mobile object. The main results are the following two points.(1) Technology of Radio communication using the weak electro-magnetic wave :An injection/extraction circuit of both mode signals and an antenna coupler that was necessary to excite a power-line antenna efficiently were developed. Moreover, to maintain the antenna efficiency, it was proposed to adopt the shielded AC cord of the PLC modem. These results were applied for as a patent.(2)Technology of highly accurate localization :An indoor highly accurate localization by audible frequency DS-CDM and its accuracy were examined, where the navigation of the home robot was assumed. By using the technology (1) of weak Radio wave to synchronize the mike and speakers, the proposed localization technology achieved the accuracy of several cm under the environment where a lot of obstacles existed in a room.These results were written in three papers presented at international conferences, and published as an invited paper and a tutorial paper.

传统的电力线通信(PLC)是一种在100伏的线路之间注入通信信号的通信方式，该注入方式称为常模注入。另一方面，所提出的注入方法是在 100V 线和大地之间进行的，称为幻象模式注入。注入的幻像模式信号从 100V 线路发射到空间。如果在房间这样的封闭空间中布线许多线路，就会充满微弱的电磁场，从而使无线电通信成为可能。在这种情况下执行的通信被称为“有线和无线电融合型PLC”。本研究采用融合型PLC系统来实现室内移动物体的高精度定位。主要成果有以下两点。 (1)利用弱电磁波的无线电通信技术：开发了有效激励电力线天线所需的双模信号注入/提取电路和天线耦合器。 。此外，为了保持天线效率，建议采用PLC调制解调器的屏蔽AC线。这些成果已申请专利。 (2)高精度定位技术：以家庭机器人导航为前提，对基于可听频率DS-CDM的室内高精度定位及其精度进行了检验。通过使用弱无线电波技术（1）来同步麦克风和扬声器，所提出的定位技术在房间内存在大量障碍物的环境下实现了几厘米的精度。这些结果写在三篇论文中，发表于国际会议，并作为特邀论文和教程论文发表。
