COMMUNICATION MODULE AND COMMUNICATION SYSTEM

The embodiments of the present application provide a communication module and a communication system. The communication module comprises a combining/splitting unit and a digital-to-analog conversion unit, wherein the combining/splitting unit is connected to the digital-to-analog conversion unit, and a digital signal is transmitted between the combining/splitting unit and the digital-to-analog conversion unit; the combining/splitting unit is used for synthesizing multi-carrier signals into one digital signal in a first transmission direction and transmitting the digital signal to the digital-to-analog conversion unit, and splitting one digital signal received from the digital-to-analog conversion unit into multiple multi-carrier signals in a second transmission direction; and the digital-to-analog conversion unit is used for converting the digital signal, which is received from the combining/splitting unit, into an analog signal in the first transmission direction, and converting the received analog signal int
