Embodiment Construction

[0037] FIG. 1 shows a transmit power control module 101 and a configuration interface 106 connected thereto. In this particular embodiment, the transmit power control module 101 is incorporated in a VDSL modem connected to the DSLAM at the central office, while the configuration interface 106 is part of the operator's network management platform. In a typical setup, the operator would determine the values ​​of parameters X and Y for each subscriber or group of subscribers according to the VDSL standard specification, and configure these values ​​via the configuration interface 106 . When the user turns on his VDSL modem, the parameters X and Y are sent to the modem. A VDSL modem will use the X and Y values ​​to calculate the transmit power for upstream transmissions.

[0038] Calculation unit 102 will receive the values ​​of X and Y, and according to the formula PSD 1 ( f ) = ...

Abstract

A module (101) for controlling the transmit power of a signal transmitter. The output power is determined from a first contribution based on a first set of parameters configured by an operator and a second contribution based on a second set of parameters. The module (101) is able to configure the second set of parameters based on the first set of parameters.

Description

technical field [0001] The present invention generally relates to the control of transmit power, and more particularly relates to the configuration of control parameters for Power Spectral Density (PSD) in digital communication systems, such as uplink or downlink communications on DSL lines. Background technique [0002] An important problem in digital communication is crosstalk between multiple communication lines. Crosstalk is the effect that information transmitted on a first communication line affects a nearby second communication line due to electromagnetic radiation. Noise induced in the second line can affect information transmitted on the second line. Typically, one transmission line in a large bundle of transmission lines is affected by crosstalk from all other lines in the bundle. Induced crosstalk increases with transmit power or PSD. [0003] The length of a communication line plays an important role in the effect of crosstalk on that line. When the transmitt...
