Abstract:
A method and an apparatus for controlling a transmit signal of a radio frequency power amplifier are provided. The method includes: adjusting a power supply voltage of the power amplifier to an efficiency point power supply voltage under designated transmit power; querying correspondence between an input voltage and transmit power at each power level under the efficiency point power supply voltage; and adjusting, according to the correspondence, an input voltage to an input voltage corresponding to the designated transmit power. The embodiments of the present invention, the power amplifier is enabled to work at an optimum efficiency point while the transmit power of the power amplifier is under control, which improves efficiency of the power amplifier.
Abstract:
An input method, including: receiving input end indication information sent by an input module, where the input end indication information indicates that input of a character or a word ends; obtaining a location of a cursor; identifying the input character or word forward from the location of the cursor until a first punctuation input before the character or the word is identified; using the identified character or word as a previous text, and querying a word library for a next text associated with the previous text; and outputting the associated next text to a display module for displaying.
