Power line communication system

摘要

A communication control portion ( 11 ) performs most of communication processing performed by a communication apparatus ( 1 ). The communication control portion ( 11 ) also executes communication with another communication apparatus ( 1 ) using a communication parameter determined by a communication parameter determination portion ( 13 ). A transmission line estimation portion ( 12 ) measures characteristics of a transmission line ( 2 ) at a predetermined timing and regarding a predetermined section, and estimates the state of the transmission line ( 2 ). The communication parameter determination portion ( 13 ) newly generates an optimum communication parameter from a plurality of communication parameters obtained based on an estimation result obtained on the transmission line ( 2 ) by the transmission line estimation portion ( 12 ).
