Abstract

The invention relates to a receiving device. The receiving device comprises a radio frequency; an interference elimination unit which is used for receiving the first signal from the radio frequency and outputting a second signal; a baseband; an interference detection unit which is used for detecting whether continuous wave interference exists in the first signal and / or the second signal; an interference elimination control unit; when the interference detection unit detects that continuous wave interference exists in the first signal and / or the second signal; the interference detection unit sends detected continuous wave information to the interference elimination control unit; the interference elimination control unit processes the information of the continuous waves to obtain a first local oscillation frequency; the interference elimination unit is used for eliminating interference according to the received first local oscillation frequency; and the frequency of the continuous wave isshifted to zero center frequency, the interference elimination unit outputs a third signal, the interference elimination control unit performs continuous wave interference judgment according to the third signal, and if the judgment result is that continuous wave interference exists, the interference elimination unit eliminates the continuous wave interference in the first signal according to thethird signal and outputs a second signal.

Description

technical field [0001] The present application relates to the field of signal processing, and in particular to a receiving device, a terminal device and a computer-readable storage medium. Background technique [0002] Nowadays, signal processing technology is developing faster and faster, but in actual work, there are still problems of continuous wave interference in the signal. Contents of the invention [0003] In view of this, the present invention provides a receiving device, a terminal device and a computer-readable storage medium. [0004] In one aspect, the present application provides a receiving device, including: [0005] radio frequency; [0006] The interference elimination unit is connected to the radio frequency, receives the first signal from the radio frequency, and outputs the second signal; [0007] The baseband is connected to the interference elimination unit; [0008] An interference detection unit, connected to the continuous wave interference el...
