Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A predistortion device, comprising a predistortion unit, and the predistortion device further comprises: a signal acquiring unit connected to a transmitting circuit configured process an output signal of the transmitting circuit so as to obtain a distorted signal, the distorted signal being an out-band distorted part in the output signal of the transmitting circuit; a signal coupling unit configured to couple the distorted signal acquired by the sign…
