Document Type and Number:

WIPO Patent Application WO/2016/106508

Kind Code:

A1

Abstract:

A control method and apparatus for a DPD correction coefficient, which are applied to a microwave communication device comprising an analogue module and a digital module, and can ensure a DPD correction effect. The method comprises: according to a DPD correction coefficient corresponding to at least 2N pre-obtained typical working states of an analogue module, adopting an interpolation method to determine a designated DPD correction coefficient corresponding to a designated working state of the analogue module, wherein N characterizes the number of parameters of the working state of the analogue module; and according to the determined designated DPD correction coefficient corresponding to the designated working state of the analogue module, controlling the DPD correction coefficient.
