Problems solved by technology

In this way, when there is data transmission on the #2 twisted pair, the noise induced on the #2 twisted pair on the #1 twisted pair will be greater than the noise induced on the #5 twisted pair
If MIMO technology is applied to #1 twisted pair and #5 twisted pair, the system needs to distinguish the useful differential signal on the virtual channel from the noise on the induced #2 twisted pair, which will cause a significant decline in the performance of MIMO technology

Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] The remote MIMO method provided by the embodiment of the present invention, such as figure 1 shown, including:

[0027] S301. In a backbone network containing multiple twisted pairs, transmit data using DSL technology; the multiple twisted pairs in the backbone network will be branched towards each user when approaching the users.

[0028] Here, the so-called "close to the user" means that in the backbone network, multiple twisted-pair wires transmit d...

Abstract

An embodiment of the present invention relates to the field of communication. Provided are a multiple input and multiple output (MIMO) method, junction box and system, capable of reducing the impact on the MIMO technical performance due to the actual cabling. The remote MIMO method comprises: transmitting data using digital subscriber line (DSL) technology in a backbone network comprising a plurality of twisted pairs; branching lines for multiple users when the plurality of twisted pairs are near to the users; transmitting data using MIMO technology in the cable network from the branching point to the user. The embodiment of the present invention is used for realizing remote MIMO technology.

Description

technical field [0001] The invention relates to the communication field, in particular to a remote multiple-input multiple-output method, a junction box and a system. Background technique [0002] With the rapid development of the Internet and the rapid promotion of multimedia services, the demand for network bandwidth is increasing. In the field of broadband access, although the development trend is "optical in and copper out", there are a large number of twisted pairs in the existing network, and the laying of the fiber-to-the-home network also requires a long process. Therefore, the DSL (Digital Subscriber Line, Digital Subscriber Line) technology will remain one of the mainstream broadband access technologies for quite a long time. [0003] In order to improve the transmission bandwidth of DSL technology, the standard of ITU-T has been developed from 8Mbps (downlink) of ADSL (Asymmetric Digital Subscriber Line) to 24Mbps of ADSL2+, VDSL (Very High Speed ​​Digital Subscr...
