Problems solved by technology

[0003] However, the UFMC modulation system is faced with the problem of higher peak-to-average power ratio PAPR. High PAPR will cause signal distortion, increase out-of-band radiation, and reduce the working efficiency of the amplifier, which seriously affects the performance of the UFMC modulation system.
[0004] For the technical problem of high PAPR in the UFMC modulation system in related technologies, no effective solution has been proposed

Abstract

The invention discloses a signal processing method and device, a storage medium and an electronic device.The method comprises the steps that a first target signal and V first phase factors are taken, and V is a natural number larger than or equal to 2; obtaining a target phase factor sequence according to the V first phase factors; and processing the first target signal by using the target phase factor sequence to obtain a second target signal. By adopting the technical scheme, the technical problem that the PAPR in the UFMC modulation system is relatively high is solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a signal processing method and device, a storage medium and an electronic device. Background technique [0002] At present, several multi-carrier candidate waveforms have appeared in 5G. As one of the candidates for 5G multi-carrier modulation system, the universal filter bank multi-carrier UFMC modulation system has attracted much attention because of its excellent performance. [0003] However, the UFMC modulation system faces the problem of higher peak-to-average power ratio PAPR. High PAPR will cause signal distortion, increase out-of-band radiation, and reduce the working efficiency of the amplifier, which seriously affects the performance of the UFMC modulation system. [0004] For the technical problem of high PAPR in the UFMC modulation system in the related art, no effective solution has been proposed yet. Contents of the invention [0005] Embodiments of the presen...
