Abstract

The invention discloses a wireless signal compensation method and device, a numerical value determination method and device, equipment and a storage medium. The wireless signal compensation method isused to compensate wireless signals, and comprises the steps of: obtaining a group of target parameter values of a corresponding fitting function for wireless signal compensation according to the current state information, wherein the group of target parameter values comprises a first number set for amplitude compensation and / or a second number set for phase compensation; determining a target compensation coefficient of at least one frequency component of the wireless signal according to the fitting function and the group of target parameter values; and compensating the corresponding frequencycomponent in the wireless signal by using the target compensation coefficient of each frequency component to obtain a target signal.

Description

technical field [0001] The embodiments of the present application relate to communication technologies, and relate to but are not limited to wireless signal compensation methods, value determination methods and devices, devices, and media. Background technique [0002] In modern wireless communication systems, various signal processing processes including filtering, and physical devices such as digital-to-analog / analog-digital converters, analog filters, power amplifiers, and tuners in antennas will inevitably introduce signal distortion, usually in the form of It is the non-flatness of the amplitude response in the frequency domain and the nonlinearity of the phase response within the effective bandwidth of the signal. This frequency domain distortion will affect the quality of the transmitted signal or the received signal to a certain extent, and affect the performance of communication transmission. [0003] Generally, the method for correcting such frequency domain disto...
