Abstract

A signal processing method and device are used to obtain multi-band signals that enable a dual-input power amplifier to achieve high working performance during amplification. The device can decompose and combine analog radio frequency signals of at least two frequency bands by using an analog signal decomposition apparatus and a combination apparatus, to obtain two paths of multi-band signals whose spectra include the at least two frequency bands. The two paths of signals satisfy nonlinearity of the dual-input power amplifier. Therefore, after the two paths of signals are input into the dual-input power amplifier, the dual-input power amplifier can achieve optimal working performance.
