Abstract
In this paper, we design and implement a high speed power-line communication modem, supported up to the transmission rate of 480kbps in a lower frequency band of under 450kHz. The power-line channel model is discussed in the sense of the lower frequency band, and the transmission technique of OFDM(Orthogonal Frequency Division Multiplexing) is considered to improve the throughput effectively. According to the power-line channel variation, the designed modem can select the modulation mapping between a 16-QAM(Quadrature Amplitude Modulation) or a QPSK(Quadrature Phase Shift Keying). Thus, it makes a sufficient QoS even in a poor channel environments. With a implementation result, we show that it gives a variable transmission rate of 480kbps or 240kbps in the signal bandwidth of $50kHz{\sim}450kHz$.
