Abstract (in Japanese) (See Japanese page) 
(in English) Phase transfer functions of power-line channels often show sharp and
periodic variation synchronous to the (double of) mains frequency.
This is a result of impedance change of nonlinear devices connected to
the power-lines. This manuscript proposes a phase estimation strategy
for phase compensation at a receiver under such environment.
In the proposed method, phase estimates are calculated using cyclic
observation (average) of the channel characteristics. The numerical
examples under periodic phase variation of the channel and
cyclostationary noise, show that the receiver with the proposed phase
estimation scheme outperforms that with the conventional phase
estimation which uses average over the whole observation period
without considering the periodic feature of the channel.
