摘要

The article mainly discusses the method of reducing PAPR of multi-carrier modulation transmitters in portable application. We firstly discussed the phase noise in OFDM system by power-supply disturbance, and some common algorithms to suppress PAPR. Further we propose an improved structural circuit of the non-capacitor LDO in the transmitter power supply, which can regulate the power load capacity to improve PAPR performance of OFDM transmitter. Based on the statistical information on sending data and precoder, we demonstrate that the power circuit can maintain a fast response and a lower average energy consumption. In addition, tests have shown that the proposed LDO circuit can maintain stable output voltage under conditions of rapid switches in load current values.
