Claim 3:
4. The method according to claim 1, wherein the sending signal is time reversal-filtered in the following manner:, y
    ⁡
    (
    t
    )
   
   =
   
    
     x
     ⁡
     (
     t
     )
    
    ⊗
    
     (
     
      K
      ·
      
       
        h
        *
       
       (
       
        -
        t
       
       )
      
     
     )
    
   
  
  ,, wherein
y(t) indicates the time reversal-filtered sending signal, x(t) indicates the sending signal, h*(−t) indicates time reversal filtering on x(t), h*(−t) indicates a conjugate of h(−t), h(−t) indicates time reversal of h(t), h(t) indicates an impulse response to a residual self-interference channel obtained after the first-level self-interference reconstruction signal is canceled from the radio frequency signal received by the receive antenna, and K is a normalized coefficient.
