Method and device for secured sharing of signals for crosstalk cancellation

A communication apparatus configured to enable reducing interferences in communications exchanged along a plurality of communication channels operated by a first operator that are caused by one or more alien communication channels operated by a second operator, and wherein the communication apparatus comprises:

• (i) a receiver operative to receive, from the first operator, information that relates to interferences experienced by the plurality of communication channels, due to traffic conveyed along the one or more alien communication channels;
• (ii) a processor operative to modify original signals conveyed along the one or more alien communication channels, and wherein the modified signals are adapted to enable when applied to communications exchanged along the plurality of communication channels operated by the first operator, to substantially reduce interferences therein that are caused by the one or more alien communication channels;
• and
• (iii) a transmitter operative to send the modified signals so that they can be applied to communications exchanged along the plurality of communication channels.
