Abstract: A method includes: a first device sends a first data frame to a second device, where the first data frame includes an LFMS a1; the first device receives a mixed signal, where the mixed signal includes a first reflected data frame of the first data frame and a second data frame sent by the second device; the first device obtains a first offset based on the LFMS a1 in the first reflected data frame, and obtains a reconstructed data frame of the first reflected data frame based on the first data frame; and the first device eliminates the reconstructed data frame of the first reflected data frame from the mixed signal based on the first offset.
