Summary:The present invention discloses a self-interference channel estimation method and device, where the method includes: determining, by a first device when a receive port of the first device receives a first signal, a second signal transmitted by a transmit port of the first device, where the first signal includes a service signal that a second device sends to the first device, and includes a self-interference signal of interference that the second signal transmitted by the transmit port of the first device causes, through an air interface, to the service signal received by the receive port of the first device, where service data included by the second signal is segmented into at least two segments, and a signal sequence formed by at least one preset character is inserted between the at least two segments of service data; estimating, according to the first signal and the second signal, the self-interference signal of interference that the second signal transmitted by the transmit port of the first device causes, through the air interface, to the service signal received by the receive port of the first device; and eliminating the self-interference signal from the received first signal. Interference that the self-interference signal causes to the service signal received by the receive port is effectively suppressed, and system performance is improved.
