Title:
PRE-DISTORTION PROCESSING DEVICE, SIGNAL TRANSMISSION SYSTEM, AND PRE-DISTORTION PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/129494
Kind Code:
A1
Abstract:
A pre-distortion processing device, a signal transmission system, and a pre-distortion processing method. The pre-distortion processing device comprises a pre-distortion unit (101), a transmission unit (102) and a coupling unit (103) which are sequentially connected. A feedback path (104) of the coupling unit (103) is connected to the pre-distortion unit (101). The pre-distortion processing device further comprises a generation unit (105) and a combiner unit (106). The generation unit (105) is used to generate a non-hopping wideband signal having a bandwidth greater than a bandwidth of a system input signal. A first input end of the combiner unit (106) is connected to an output end of the generation unit (105). A second input end of the combiner unit (106) is used to receive the system input signal. An output end of the combiner unit (106) is connected to an input end of the pre-distortion unit (101).
