Abstract
A communication system includes a baseband circuit, a transmitting end circuit, and a receiving end circuit is disclosed. The transmitting end circuit includes a digital analog conversion circuit and a transmitting end filtering circuit. The receiving end circuit includes a receiving end amplifying circuit, a receiving end filtering circuit, and an analog digital conversion circuit. A first data signal is transmitted to the analog digital conversion circuit through the digital analog conversion circuit and the transmitting end filtering circuit, so that the baseband circuit obtains a first compensation parameter. A second data signal is transmitted to the receiving end filtering circuit, the receiving end amplifying circuit and the analog digital conversion circuit through the digital analog conversion circuit and the transmitting end filtering circuit, so that the baseband circuit obtains a second compensation parameter. The baseband circuit performs calibration according to the first and the second compensation parameter.
