Problems solved by technology

[0009] However, this kind of power management mainly focuses on whether the user is really online and whether there is user data flow, rather than paying attention to the change of line conditions. It also cannot realize the dynamic change of transmission power with the change of line conditions.

Embodiment Construction

[0048] The core of the present invention is to monitor the noise margin of the signal and adjust the noise margin of the signal by adjusting the signal transmission power according to the monitoring results, so as to realize the premise of meeting the rate and noise margin (margin) required by the user, The transmission power is dynamically adjusted according to changes in line conditions (insertion loss, background noise, etc.), so that the transmission power is minimized, thereby reducing crosstalk and device power consumption.

[0049] The idea of ​​the seamless dynamic power adjustment (STPA) proposed by the present invention is fixed rate configuration, and when the line condition changes, the margin is kept within a certain range by reducing or increasing the transmission power.

[0050] The method described in the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0051] The following parameters are introduced in t...

Abstract

The invention relates to a seamless sending power adjusting method and relative system. Wherein, it comprises: detecting the noise allowance of received signal and comparing the detected result with the range of noise allowance; when the time that signal noise allowance over said range is over preset value, via adjusting the signal sending power, adjusting the noise allowance to the target noise allowance range. Therefore, the invention can adjust the sending power of modulator / demodulator with the change of noise allowance in fixed speed, to confirm the stability and low error code rate in data transmission, to minimize the sending power and reduce the crossfire.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a seamless transmission power adjustment method and system. Background technique [0002] In communication systems, Digital Subscriber Line Access (xDSL) is a network access technology widely used at present. This is a high-speed data transmission technology applied to unshielded telephone twisted pair (Unshielded Twist Pair, UTP) transmission, which contains a variety of specific technical solutions, in addition to Internet Digital Subscriber Line (IDSL) and single-pair high bit rate In addition to digital subscriber line (DSL) transmitted by baseband such as digital subscriber line (SHDSL), xDSL of passband transmission uses frequency division multiplexing technology to make xDSL and traditional telephone service (POTS) coexist on the same pair of twisted pairs, of which xDSL occupies In the high frequency band, POTS occupies the baseband part below 4KHz, and th...
