    Abstract: PROBLEM TO BE SOLVED: To provide a power-line communication method, a power-line communication device, and a power-line communication system, which can make communication carry out at high communication efficiency, even if the conditions of a power line are changed. SOLUTION: In step S101, noise condition is detected in correspondence to a time domain synchronized with a power source cycle of a power line. In step S102, a communication channel generation process for generating communication channels in the time domain is performed, on the basis of the noise condition detected in step S101. In step S103, tone maps are prepared for the communication channels generated in step S102. When the preparation of the tone maps is ended, the tone maps are transmitted to a destination PLC, and data are transmitted and received between a transmission-side PLC and a reception-side PLC by the use of the same tone map (step S104).
