Claim 17:
18. The first device according to claim 16, wherein the first interference reconstruction submodule is further configured to:
obtain a kth delay parameter and a (k+1)th delay parameter, wherein the kth delay parameter is of an interference signal resulting from a kth far-end reflection, the (k+1)th delay parameter is of an interference signal resulting from a (k+1)th far-end reflection, and k is a positive integer;
determining, based on the kth delay parameter and the (k+1)th delay parameter, a length of an intermediate frequency cable that connects the first device and the second device; and
determining, based on the length of the intermediate frequency cable, that the X far-end reflected interference signal cancellations need to be performed.
