    摘要: A high-efficiency power amplifier is provided, including a drive amplifier and a final power amplifier, and further including a first digital pre-distortion (DPD) correction module and a second DPD correction module. The first DPD correction module is configured to pre-distort nonlinear characteristics of drive signals output by the drive amplifier, and the second DPD correction module is connected to the first DPD correction module in series, and is configured to pre-distort nonlinear characteristics of amplified signals output by the final power amplifier. Another high-efficiency power amplifier is also provided, including a drive amplifier and a final power amplifier, and further including a second multi-path control module, a fourth DPD correction module, and a second gating module. The overall efficiency of the high-efficiency power amplifier is increased by improving the working efficiency of the drive amplifier. Further, higher overall efficiency is also achieved for a power amplifier with a higher gain.

    摘要: A receiver and method for receiving wireless signal are characterized in that a multi-branch correcting and switching module (402) is added, which is used for amplitude and phase correction of multiple digital baseband signals outputted from a multi-branch correction preprocess module (401); then, the signals are switched according to a switching strategy, and one of the corrected digital baseband signals is outputted; finally, the selected digital baseband signal is inputted to a digital receiving path post-stage (403) and further digital processing on the signal is performed, so that a bit stream is outputted. The multiple digital baseband signals are corrected before switching to be consistent with each other in terms of amplitude and phase, and specific synchronization information is not necessary; therefore, the signals can be switched rapidly when the signals are varied and need to be switched, and a rapid track for the signal change is achieved.
