Abstract

The invention discloses a signal processing method and apparatus, a storage medium, and an electronic device. The signal processing method comprises the following steps: when a wireless fidelity module transmits a wireless signal, acquiring an original band edge signal of a current channel and acquiring a maximum peak signal in the original band edge signal; when the peak value of the maximum peaksignal of the original band edge signal reaches a first preset peak value, storing the original band edge signal in a register, adjusting configuration parameters of the register, and obtaining an output signal of the register, wherein the output signal is a phase-shifted signal generated after the original band edge signal is output through the register; and obtaining a first processing signal by performing combining processing on the output signal and the original band edge signal. According to the invention, the band edge signal is optimized by modifying the register, the peak-to-average ratio of a wireless communication module can be reduced, and the sideband suppression of the band edge signal of the wireless communication module is increased.

Description

technical field [0001] The present application relates to the technical field of mobile communication, in particular to the technical field of mobile equipment, and in particular to a signal processing method, device, storage medium and electronic equipment. Background technique [0002] At present, with the development of mobile communication technology, wireless fidelity (Wireless Fidelity, WiFi) technology has become a standard function of most communication electronic devices. [0003] In order to bring better experience to users, improve signal quality, increase the transmit power and receive sensitivity of electronic equipment has become the trend of most mainstream equipment manufacturers. However, due to the influence of the linearity of the device itself, too much increase in power will also affect the linearity of the power amplifier, which is prone to clutter. Therefore, further improvement is required. Contents of the invention [0004] Embodiments of the pre...
