| Abstract(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. |
