<p>Disclosed are a radio-frequency signal control method and device. The method mainly comprises: by adjusting a down-conversion first gain attenuation value and using the adjusted down-conversion first gain attenuation value, changing an input radio-frequency signal, and/or through a determined linear filtering parameter, conducting linear improvement on a digital signal formed by conducting down-conversion and analogue-to-digital conversion on the input radio-frequency signal; and after the digital pre-distortion processing is conducted, using an increased up-conversion gain attenuation value to correct the radio-frequency input signal on which the digital pre-distortion processing is conducted, to allow the adjusted and/or improved signal to be output after a power amplification operation, and to allow the signal quality of the adjusted radio-frequency signal to be better than that of a radio-frequency signal on which the analogue-to-digital conversion and peak clipping processing are conducted singly, thereby improving the linear effect of the radio-frequency signal on which the digital pre-distortion processing is conducted, and the dynamic effect of a power amplification operation, and improving the coverage effect of a radio-frequency output signal.</p> |
