Predistortion device, method for predistortion, and transmitter/receiver system that reuse an analog receiving circuit in a half duplexing system and a full duplexing system, and that reduce the requirement on the analog receiving circuit
The embodiments of the present invention provide a predistortion device, method for predistortion and transmitter/receiver system. The predistortion device comprises a predistortion unit, and the predistortion device further comprises: a signal acquiring unit to process the output signals of a transmitting circuit to obtain distorted signals; a signal coupling unit to couple the distorted signals acquired by the signal acquiring unit to the receiving signals inputted to a receiving circuit; and a signal processing unit to decouple the output signals of the receiving circuit to acquire the distorted signals and the receiving signals. With the embodiments of the present invention, an analog receiving circuit may be reused in a half duplexing system and a full duplexing system, and the requirement on the analog receiving circuit is lowered, thereby reducing the cost.
