| description | The present application relates to the technical field of communications, provides a signal processing apparatus and a communication device, and is used for improving the cancellation precision of a nonlinear distortion signal. The apparatus comprises: a first branching module, a first combining module, a time delay device, and a filtering circuit. The first branching module is coupled with a signal source of the signal processing apparatus, and an output end of the first branching module is separately coupled with an input end of the time delay device and an input end of the filtering circuit; an output end of the time delay device is coupled with a first input end of the first combining module; an output end of the filtering circuit is coupled with a second input end of the first combining module; the filtering circuit comprises a plurality of filtering sub-circuits and an accumulation circuit, and output ends of the plurality of filtering sub-circuits are coupled with an input end of the accumulation circu |
