Abstract

Method and device for data processing and communication system with such a device. The method and the device allow data processing via at least one channel. The method includes the following step of transmitting an idle pattern across the at least one channel when no information is conveyed. The idle pattern is created such that interference and/or crosstalk resulting from the idle pattern can be reduced at the receiving side.

Claims

1-16. -16. (canceled)

17. A method for data processing via at least one channel, the method which comprises the following steps:

transmitting an idle pattern across the at least one channel to a receiving side when no information is being conveyed;

creating the idle pattern such that interference and/or crosstalk resulting from the idle pattern can be reduced at the receiving side.

18. The method according to claim 17, which comprises conveying an identical idle pattern for each channel.

19. The method according to claim 17, wherein information to be conveyed over the at least one channel is pre-processed such that interference and/or crosstalk can be reduced at the receiving side.

20. The method according to claim 17, which comprises actively pre-coding at a central office for each channel that conveys information towards a customer premises equipment.

21. The method according to claim 17, which comprising carrying out interference and/or crosstalk cancellation at the receiving side.

22. The method according to claim 17, wherein the at least one channel is at least one communication channel.

23. The method according to claim 17, wherein the at least one channel is at least one wireless channel.

24. The method according to claim 17, wherein the at least one channel is at least one wireless and/or fixed connection between a central office and/or a digital subscriber line access multiplexer and at least one customer premises equipment at the receiving side.

25. The method according to claim 17 implemented in a communications network.

26. The method according to claim 17, wherein the at least one channel comprises at least one fixed point to multi-point connection.

27. The method according to claim 26, wherein the fixed point to multi-point connection comprises at least one stationary or quasi-stationary positioning of a base station of a central office and/or of a user terminal.

28. The method according to claim 17, wherein the idle pattern is known to the receiver at the receiver end.

29. The method according to claim 28, wherein the idle pattern is known to the CPE(s) at the receiver end.

30. A data processing device, comprising a processor unit including a processor programmed to execute the method according of claim 17.

31. A data processing device, comprising a processor unit including a processor programmed to execute the method according of claim 17 for reducing or canceling interference and/or crosstalk in a transmission line.

32. The device according to claim 31, configured as a communication device.

33. The device according to claim 32, configured as a Central Office communication device.

34. The device according to claim 32, configured as a digital subscriber line access multiplexer.

35. The device according to claim 30, configured as a customer premises equipment.

36. A communication system, comprising data processing device with a processor programmed to execute the method according of claim 17 for reducing or canceling interference and/or crosstalk.
