The invention provides a receiver and a calibration method of direct-current information. The receiver comprises a feed-forward module, a feedback module, an estimation module and a calibration module, wherein the feedback module is used for obtaining the direct-current error value of the receiver and judging whether the direct-current error value is greater than a direct-current estimation threshold or not; if the direct-current error value is greater than the direct-current estimation threshold, it is determined that the estimation module is in a capturing state, and a first control signal is sent to the estimation module; if the direct-current error value is smaller than the direct-current estimation threshold, it is determined that the estimation module is in a tracking state, and a second control signal is sent to the estimation module; the estimation module is used for obtaining a first gain factor and a second gain factor according to the received first control signal, and according to the first gain factor and the second gain factor, a feed-forward direct-current estimated value and a feedback direct-current estimated value are combined to obtain the direct-current information; alternatively, a third gain factor and a fourth gain factor are obtained according to the second control signal, and the feed-forward direct-current estimated value and the feedback direct-current estimated value are combined to obtain the direct-current information according to the third gain factor and the fourth gain factor. According to the receiver and the calibration method, parameter estimation does not need to be carried out on a lot of data, and rapid direct-current capturing and tracking properties can be obtained.
