要約(英語): The interference with existing radio broadcasting services because of unintentional radiation is a serious problem in power-line communication (PLC) systems. A radiation detection method based on burst packets, which had been proposed by the authors and was called scan and sum (SAS) method, was a low cost method and used to solve the problem. But its measurement took a long time and the burst packets occupied a channel. To shorten the measurement time, a new method based on periodic packets has been proposed in this paper, which is called periodic packet sound (PPS) method. Although both methods record the radiated signal as a sound data, the PPS does not need to scan the frequency of an AM radio receiver but analyses the sound data by a cross-correlation operation with a reference signal. First, how to generate the reference signal that depends on the modems is described. Second, an optimization of the packet size is studied, and finally it is shown that the detection sensitivity of PPS was maintained to be the same as SAS while the measurement time of PPS was 1/9 shorter than that of SAS. Moreover, the channel occupation of PPS was reduced to be 2% of SAS when the packet size was optimized to be 1500 bytes.
