<p>Disclosed are a control method and device for a radio-frequency signal, the main content of which is: by changing a gain attenuation value in real time, adjusting an input radio-frequency signal utilizing the gain attenuation value changed in real time, and/or by determining a linear filtering parameter, performing linear improvement on the digital signal of the input radio-frequency signal subjected to down-conversion and analogue-to-digital conversion, and outputting the adjusted and/or improved signal subjected to digital pre-distortion processing and power amplification. Compared with the prior art, an input radio-frequency signal is adjusted by means of an adjusted gain attenuation value, and/or the input radio-frequency signal is subjected to linear improvement, so that the signal quality of the adjusted radio-frequency signal is better than that of a radio-frequency signal singly subjected to analogue-to-digital conversion and peak clipping processing, thereby improving the linear effect of the radio-frequency signal subjected to digital pre-distortion processing and the dynamic effect of a power amplification operation, and improving the coverage effect of a radio-frequency output signal.</p> |
