POWER AMPLIFIER PRE-DISTORTION ADAPTATION METHOD AND THE CIRCUIT USING THE COMPRESSION DETECTION PREVENTING THE LOSS DUE TO THE EXCESSIVE ELECTRICAL ENERGY CONSUMPTION

摘要

PURPOSE: By simply adjusting the forward path gain the power amplifier pre-distortion adaptation method and the circuit using the compression detection regularly correct pre-distortion.;CONSTITUTION: According to the pre-distortion correction value which the pre-distortion circuit(310) is selected from a plurality of pre-distortion correction values, the input signal is distorted. The transceiver circuitry processes the output signal received from the pre-distortion circuit. The amplifier circuit amplifies the output signal received from the transceiver circuitry.;COPYRIGHT KIPO 2011
