Abstract (in Japanese) (See Japanese page) 
(in English) Power-line Communication(PLC) based local area network(LAN) in ships are one of the promising applications of the PLC technology.
In this paper, the delay profiles have been analyzed from the transfer function of 100V power-line channels of residence area in ships and that of 440V power-line channels for reefer containers, which had been measured by the authors.
It was found that the characteristics of the delay spread were able to
be approximated by a liner function of which the parameters were the
length of cable and the delay spread in distribution panels.
The cumulative distribution of delay time has also been calculate, and
the required guard-interval value for the OFDM system in ships has been
shown.
In addition, the area where the signal attenuation of common-mode transmission becomes less than that of differential-mode has been studied from the channel model of attenuation.
