“…Therefore PLC is the economical and convenient communication method, because new transmission line to be installed is not needed, and connection to the network is possible just plugging PLC modem to power outlet (12) (13) . The OFDM (Orthogonal Frequency Division Multiplexing) is one method to realize high speed communication, and the relation between transmission loss characteristic of power line and transmission rate of OFDM signal in several branch models of power line is reported (14)- (19) . There are many radio systems, which emit strong radio wave and interferes PLC system, such as radio equipment for a plane and ship, ham radio.…”

“…PLC is an excellent system from the aspect of economy and convenience, because new transmission line to be installed is not needed, and connection to the network is possible just connecting PLC modem to outlet (Plug & Play) [1] [2] . In such a background, many empirical experiments with PLC modem by using OFDM (Orthogonal Frequency Division Multiplexing) modulation method have been conducted, and the relation between transmission loss characteristic of power line and transmission rate of OFDM signal in several branch models of power line have been reported [3]- [8] .…”

In this paper, we measured the interference immunity characteristics of high-speed PLC modem using Wavelet-OFDM when the narrowband conducted interference signal was injected, and also calculated them by the computer simulation using MATLAB/ Simulink. As the results, it was clear that (1) measured PHY rate at the all frequency band hardly decreased in C/I of more than -10dB, but began to decrease rapidly in C/I of less than -30dB when the interference signal was injected in the frequency band of PLC signal, (2) when C/I became -60dB, the measured PHY rate at the frequency existing the notch band were improved around 10Mbps than that at the frequency not existing the notch band, (3) when the narrowband interference wave was injected outside of PLC frequency band, the measured PHY rate did not decrease than that in each notch band, (4) calculated PHY rate at the frequency existing the notch band were improved around 10Mbps than that at the frequency not existing the notch band, when C/I became below -10dB. Therefore, it was revealed that Wavelet-OFDM PLC system had good interference immunity characteristics.

In this paper, we calculated the immunity characteristics of PLC system to the conducted interference wave, from the aspect of PHY rate (physical layer data rate) by using MATLAB/Simulink, and compared with measurement results. As the results, it is revealed that the PHY rate of PLC modem can be calculated by using MATLAB/Simulink as well as the measurement one even when the narrowband interference signal is impressed through the power line. In addition, we can confirm by using MATLAB/Simulink that the PHY rate normalized by the maximum value increases by about 20% by inserting the notch when impressing the interference signal in the notch band and C/I is improved by 10~15dB by inserting the notch.
