Abstract: The application relates to the field of communications technologies, and disclose a signal amplification processing method and apparatus. The method includes setting multiple groups of parameter values for a signal decomposition parameter group, separately performing signal amplification processing based on each group of parameter values, obtaining a power amplification efficiency corresponding to each group of parameter values, obtaining a group of parameter values corresponding to a maximum power amplification efficiency in the power amplification efficiency corresponding to each group of parameter values, and setting the group of parameter values corresponding to the maximum power amplification efficiency as parameter values of the signal decomposition parameter group. Thus, the power amplification efficiency may be improved.

Abstract: Embodiments of the present invention provide a transmitter. The transmitter includes: a dual-band input circuit including at least two band input ends, performing DPD processing on an input baseband signal, and outputting the baseband signal; a modulo circuit, performing modulo processing on the input baseband signal, and outputting the baseband signal; a signal decomposition circuit, receiving the baseband signal input by the dual-band input circuit and a baseband signal modulus value input by the modulo circuit, and performing decomposition to obtain multiple decomposed signals; a modulation circuit, receiving the multiple decomposed signals, performing processing, modulating two signals obtained after processing to corresponding working frequencies, and outputting the two signals to a dual-band power amplifier. In comparison with a single-input dual-band power amplifier, when a dual-input dual-band power amplifier transmits signals in two bands concurrently, overall transmission efficiency of a dual-band transmitter can be obviously improved.
