Abstract
A multi-channel predistortion method and apparatus are disclosed. The technical method provided in the embodiment of the present invention includes: determining a channel index of a current channel to be processed; performing handover to the current channel according to a determined channel index; collecting forward data and reverse data of the current channel, and estimating a predistortion coefficient; and performing predistortion compensation on forward data of each channel according to a corresponding predistortion coefficient. In the embodiments of the present invention, by using a jumping polling mode on a channel time, the predistortion efficiency under multiple channels is improved. In addition, by means of all channels or a plurality of channels sharing N power levels, the resource utilization rate is improved.
