| description | This application provides a signal processing apparatus and a communication device, and relates to the field of communication technologies, to improve cancellation precision for a non-linear distortion signal. The apparatus includes a first splitter module, a first combiner module, a delayer, and a filter circuit. The first splitter module is coupled to a signal source of the signal processing apparatus, and an output end of the first splitter module is separately coupled to an input end of the delayer and an input end of the filter circuit. An output end of the delayer is coupled to a first input end of the first combiner module. An output end of the filter circuit is coupled to a second input end of the first combiner module. The filter circuit includes a plurality of filter sub-circuits and an accumulation circuit, and output ends of the plurality of filter sub-circuits are coupled to an input end of the accumulation circuit. |
