Abstract: The present invention discloses a predistortion method based on vector envelope injection. The method includes the following steps: radio frequency input signals are divided into two signal streams; one input signal stream generates two envelope injection signals whose amplitudes can be adjusted independently; the other signal stream is divided into further two radio frequency signal streams; the two radio frequency signal streams are amplified with the same amplitude; frequency mixing is performed for the two envelope injection signals and two radio frequency signal streams respectively to obtain two compensation signals; the amplified radio frequency signal and compensation signals are power synthesized in the same way, so as to obtain two compensation signals and amplified radio frequency signals of different directions. This present invention also provides a corresponding predistortion device.

Abstract: The present invention provides a customizing system and a customizing method for converting a desktop application into a web application. A required processing logic may be added by locating an interface element which is needed to be modified, and modifying a callback function of the interface element (interface description data), so as to implement user's operations on local data by a web application. When a user operates on the modified interface element at a browser side, the added processing logic automatically converts the user's operation to a plurality of operations, so that the user may feel that he is operating on a local file at the browser side, rather than a remote file at a server side. The present invention may implement complex webpage function customization, and thus may implement remote operations on local data.
