Embodiment 1
[0043] An embodiment of the present invention provides a signal processing method for binding digital subscriber line channels, such as figure 2 As shown, the method includes the following steps:
[0044] 201. Send pilot sequences to a receiving end through at least two bonded channels.
[0045] The pilot sequences should be sent simultaneously from each channel being bonded.
[0046] 202. Receive the interception error segment returned by the receiving end.
[0047]The pilot sequence transmitted through the channel generates errors due to far-end crosstalk. After the receiving end receives the pilot sequence sent by the sending end, the error caused by the far-end crosstalk of the pilot sequence is composed of an interception error, and then the receiving end slices the interception error to obtain the interception error fragmentation and returns it to sender.
[0048] 203. Re-aggregate the received truncation error fragments into truncation errors.
[0049] 204. Calcul...
Embodiment 2
[0054] The embodiment of the present invention provides a processing method for binding digital subscriber line channels, such as Figure 4 As shown, the method includes the following steps:
[0055] 401. Send a pilot sequence to a receiving end through at least two bonded channels.
[0056] The pilot sequences should be sent simultaneously from each channel being bonded.
[0057] 402. Receive the interception error segment returned by the receiving end.
[0058] The pilot sequence transmitted through the channel generates errors due to far-end crosstalk. After the receiving end receives the pilot sequence transmitted by the transmitting end through the channel, the error caused by the far-end crosstalk of the pilot sequence is composed of the interception error and the interception error is divided into interception error fragments, and then the interception error fragmentation is divided into Return to the sender. The receiving end performs fragmentation operations on th...
Embodiment 3
[0070] An embodiment of the present invention provides a signal processing device for binding digital subscriber line channels, such as Figure 5 shown. The apparatus includes: a sending unit 51 , a receiving unit 52 , an aggregation unit 53 , and a precoding calculation unit 54 .
[0071] The sending unit 51 is configured to respectively send the pilot sequence to the receiving end through the at least two bonded channels. The receiving unit 52 is configured to receive the truncation error segment returned by the receiving end. The aggregation unit 53 re-aggregates the received truncation error fragments into truncation errors. The precoding calculation unit 54 is configured to calculate a precoding coefficient according to the pilot sequence and the re-aggregated truncation error. Before the signal is sent to the at least two bonded channels, the transmitting end performs precoding processing on the signal by using the precoding coefficient.
[0072] Since the truncation...
