The utility model relates to a self-matching signal filter based on FEC error correction and impedance self-adaption, which comprises a filter main body, an automatic impedance matcher, an impedance analyzer and a comparison processor, the first end of the automatic impedance matcher is electrically connected with the input end of the filter main body, and the second end of the automatic impedance matcher is electrically connected with a transmission cable; the impedance analyzer is electrically connected with the transmission cable and the automatic impedance matcher, and the impedance analyzer adjusts the impedance value of the automatic impedance matcher according to the detected impedance value of the transmission cable; the comparison processor is electrically connected with the output end of the filter main body and simultaneously acquires an output signal sent by the terminal, and the comparison processor compares the output signal sent by the terminal with a signal filtered by the filter main body and
