Patent number: 9008163Abstract: A vectored-DSL method and system and a board relate to the field of digital subscriber line DSL data processing, so as to increase user capacity of a vectored-DSL system. The vectored-DSL method includes: receiving, by at least one board, and pre-processing user data of the board; transmitting, by the board, the user data of the board to an auxiliary vector processor on the board to perform internal vectorization processing, so as to obtain internally processed data; transmitting, by the board, the user data thereof to a centralized vector processor to perform external vectorization processing, so as to obtain externally processed data; and receiving, by the board, the externally processed data of the board, and post-processing the externally processed data and the internally processed data.Type: GrantFiled: November 18, 2013Date of Patent: April 14, 2015Assignee: Huawei Technologies Co., Ltd.Inventors: Ruijie Xiao, Huishen Dong, Cheng Li, Jinxiong Lv, Jianwei Ke

Patent number: 8711669Abstract: 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.Type: GrantFiled: May 31, 2012Date of Patent: April 29, 2014Assignee: Huawei Technologies Co., Ltd.Inventors: Liming Fang, Jie Lv, Huishen Dong

Patent number: 8468437Abstract: A filtering method, system, and equipment applied in digital communication technologies are disclosed in the embodiments of the present invention. The filtering method of the present embodiments includes: acquiring filtering coefficients of a part of all subcarriers according to data transmission errors; acquiring filtering coefficients of remaining subcarriers through an interpolation algorithm according to the filtering coefficients of the part of subcarriers; and finally, filtering the data corresponding to the multiple subcarriers according to the filtering coefficients of the part of subcarriers and the filtering coefficients of the remaining subcarriers. The part of subcarriers may be selected at a regular interval, or may be subcarriers which are located at a motion value away from the part of subcarriers selected in the previous update of the filtering coefficients. The method of the present embodiments reduces the amount of operation and hardware expenditure, and saves the cost.Type: GrantFiled: February 17, 2012Date of Patent: June 18, 2013Assignee: Huawei Technologies Co., Ltd.Inventors: Pengrui Zhang, Guozhu Long, Cheng Li, Huishen Dong, Yuchen Jia
