Classification: CPC H  Y | IPC H

Claim 11:
12. The apparatus according to claim 9, wherein the time reversal filter is configured to time reversal-filter the sending signal 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.
