Abstract
An xDSL signal transmission method includes: receiving 2N−1 signals from 2N−1 signal input ends, where each signal in the 2N−1 signals is a signal transmitted by an independent channel in the xDSL system; pre-multiplying a (2N−1)×1 matrix formed by the 2N−1 signals by a first conversion matrix to obtain a 2N×1 matrix, where elements in the 2N×1 matrix respectively correspond to 2N signals, and the first conversion matrix is a 2N×(2N−1) matrix; and sending the 2N signals via N twisted pair lines respectively. The N twisted pair lines can transmit signals of 2N−1 channels, thereby increasing the number of signal transmissions, and improving signal transmission efficiency.
