Abstract: The present disclosure relates to pre-distortion processing methods and apparatus. One example apparatus includes a first pre-distortion part and a second pre-distortion part. The first pre-distortion part includes N digital pre-distortion (DPD) processors. The first pre-distortion part and the second pre-distortion part perform pre-distortion processing on a signal to support a power amplifier in performing linear amplification on the signal.

Abstract: The present invention relates to the field of mobile communications technologies, and in particular, to a right control method, a client, and a server, so as to resolve a technical problem in the prior art that there is no method that can better control a right of a user. In embodiments of the present invention, the server can send right information corresponding to a login account to the client, so that the client controls access right of the login account, which does not cause too much burden on the server; a manner is more direct in which the client controls the access right of the login account, thereby reducing control time and generating higher control efficiency.

Abstract: A power amplifier, a radio remote unit (RRU), and a base station, where the power amplifier includes an envelope controller, a main power amplifier, and an auxiliary power amplifier. The main power amplifier and the auxiliary power amplifier both set an envelope voltage output by the envelope modulator as operating voltages, and because the operating voltages of the main power amplifier and the auxiliary power amplifier may be adjusted simultaneously, symmetry of the power amplifier is improved, and an efficiency loss occurring probability is low, thereby enhancing efficiency of the power amplifier.
