In order to solve the problem that the peak power is lower than the power efficiency of the amplifier in the system and achieve high efficiency and low power consumption, a signal decomposition and amplification technique is proposed in this paper. The signal decomposition algorithm is used to decompose the peak-to- The signal of the branch is parallelized and amplified and transmitted in parallel so as to reduce the peak-to-average ratio of the branch signal and improve the power efficiency of the amplifier. The simulation shows that the method can effectively improve the power efficiency of the amplifier in the peak-to-average ratio system.
