Method and device for processing data and communication system comprising such device
A method and a device are provided for processing first data, wherein said first data are distributed, in particular temporally spread over and/or on top of second data. In addition, a communication system comprising such device is suggested.
1. A data processing method, which comprises:
processing first data utilizing a first frequency range;
identifying lines that interfere with one another; and
distributing the first data utilizing a first frequency range over second data utilizing a second frequency range according to mutually orthogonal pseudo-random codes for those lines that show significant interference by switching discrete multitone symbols on and off.
2. The method according to claim 1 , wherein the first data are distributed according to an initial pseudo-random code.
3. The method according to claim 2 , wherein the initial pseudo-random code is a code arranged in a binary tree hierarchical structure.
4. The method according to claim 3 , which comprises prioritizing a portion of the first data associated with a certain hierarchical stage of the pseudo-random code.
5. The method according to claim 1 , which comprises defining significant interference as a value of interference above a given threshold value.
6. The method according to claim 1 , wherein the first data comprises data distributed over a plurality of lines and/or ports.
7. The method according to claim 6 , wherein the lines or ports are associated with a line-card or with a digital subscriber line access multiplexer.
8. A data processing device, comprising:
a unit configured to execute thereon the method according to claim 1 .
9. The device according to claim 8 , wherein said unit is a communications device or said unit is associated with a communication device.
10. The device according to claim 9 , wherein said unit is a line card or a digital subscriber line access multiplexer.
11. A communication system, comprising data processing device configured to execute thereon the method according to claim 1 .
