A receiver with baseline wander compensation is applicable to a digital communication system. The receiver includes an Analog-to-Digital Converter (ADC), a slicer, a threshold value detector, a gain controller, a baseline wander compensator, a delay circuit, an analog gain stage, and a digital gain stage. The baseline wander compensator is used to perform an operation and a filtering process on a voltage obtained prior to processing by the slicer and a voltage after the processing so as to obtain a baseline wander voltage value for compensation and control. The threshold value detector and the gain controller dynamically produce control signals of analog gain and digital gain. The analog gain stage compensates degrading of communication signals passing through transmission channels in an analog gain manner. The delay circuit is used to compensate the delay of the conversion performed by the ADC. The digital gain stage compensates insufficiency of the analog gain.
