<p>The invention provides a method and pre-distortion unit for correcting signals in radio frequency links. The method includes that of: based on the difference in arrival time of circular delay frames in each radio frequency link of a multiple input multiple output system, obtaining a set of pre-distortion vectors of each radio frequency link according to a time division order by using the same set of pre-distortion vector obtaining units; and correcting the subsequent signals of each radio frequency link by using the set of pre-distortion vectors. The invention can generate an error vector table in the whole dynamic power range of input signals by performing only one scan to the head of a frame, the device can be used repeatedly by using circular delay frame structure, and the high linearity in radio frequency front end is realized.</p> |
