Abstract
In a power line transmission/reception system, when a receiving device receives data via a power line transmission network which transmits the same data with the same timing in parallel via a plurality of communication channels by means of superposition on AC power, the reception of the data is performed using a communication channel selected on the basis of mean channel usage periods measured for the respective communication channels, thereby assuring high-quality communication. Transmission data is generated by converting input data into packets and outputting the same packet repeatedly. The transmission data is transmitted via the plurality of communication channels at the same time by means of multiple carriers of different frequencies superimposed on the AC power, thereby assuring high-quality data communication.
