Problems solved by technology

In fact, the required target rate is often in the rate area, and although the maximum rate can meet the rate requirement, it often requires a large transmission power, and the generated crosstalk will be relatively large, resulting in line instability. And the cost is high, and the equipment ages quickly

Embodiment Construction

[0039] 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 creative efforts fall within the protection scope of the present invention.

[0040]The DSL technology in the prior art mainly adopts the discrete multi-tone modulation (DMT) technology of frequency division multiplexing to modulate signals. Assume that there are K users (lines) in a DSL line system, using N tones (the frequency bandwidth of a tone is 4312.5Hz) to send signals, and the receiving end of each modem (modem) regards the interference of other modems to it as noise, The user's bitload on each tone is then calculated. By user bit ...

Abstract

The embodiment of the invention discloses a method, a system and a device for optimizing power. The method comprises the following steps: acquiring a sending power model of a selected route; acquiring a sending power spectrum of the route according to the sending power model, and characterizing the sending power spectrum by using a spectrum control parameter; and optimizing the sending power spectrum of the route by optimizing the spectrum control parameter. The embodiment of the invention also provides the device for optimizing the power, which comprises a sending power model acquiring module, a power spectrum acquiring module, a conversion module and a processing module, wherein the sending power model acquiring module is used for acquiring the sending power model of the selected route; the power spectrum acquiring module is used for acquiring the sending power spectrum of the route according to the sending power model; the conversion module is used for characterizing the sending power spectrum by using the spectrum control parameter; and the processing module is used for optimizing the spectrum control parameter. The method provided by the embodiment of the invention can minimize the total power under the condition of ensuring that all users achieve a target rate, save cost, and prevent the equipment from ageing.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a method, system and device for optimizing power. Background technique [0002] DSL (Digital Subscriber Line, Digital Subscriber Line) technology is a high-speed transmission technology for data transmission through telephone twisted pair, namely UTP (Unshielded Twist Pair, unshielded twisted pair), including ADSL (Asymmetrical Digital Subscriber Line, non- Symmetrical Digital Subscriber Line), VDSL (Very-high-bit-rate Digital Subscriber Line, very high-speed digital subscriber line), IDSL (ISDN Digital Subscriber Line, user digital line) based on ISDN (Integrated Services Digital Network, integrated service digital network) And SHDSL (Single-pair High-bit-rate Digital Subscriber Line, single-pair High-bit-rate Digital Subscriber Line), etc. [0003] In xDSL (various digital subscriber line technologies), in addition to DSL with baseband transmission such as ID...
