摘要：<p>A power line communication system includes first connection means (12) for connecting an inputted transmission signal to a power line, second connection means (17) for acquiring a reception signal from the power line, first communication means (2) for transmitting a transmission signal to the first connection means and reversing the transmission signal so as to generate a cancel signal, and second communication means (7) for adding the cancel signal to the reception signal received from the second connection means. By the addition of the cancel signal in the second communication means, the transmission signal from the first communication means contained in the reception signal of the second communication means is removed, thereby easily removing an unnecessary signal contained in the reception signal.</p>
