摘要：

Impedance matching plays an important role in a power-line-communication system. We investigate the effect on the signal-to-noise ratio at the receiver and on the system capacity of three different impedance matching criteria at the transmitter, assuming broad-band communication. We show that optimal impedance matching shall maximize the amplitude of the signal voltage at the channel input port. Since the line impedance exhibits highly frequency-dependent behavior, simplified impedance matching criteria are also proposed.
