Abstract:
1. A signal transmission method in an xDSL system, comprising: receiving 2N−1 signals from 2N−1 signal input ends, wherein each signal in the 2N−1 signals is a signal transmitted by an independent channel in the xDSL system; and pre-multiplying a (2N−1)×1 matrix formed by the 2N−1 signals by a first conversion matrix to obtain a 2N×1 matrix, wherein 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, wherein N is a natural number greater than 1.
