本发明专利技术提供了一种DPD系统及其实现方法。该系统包括DPD模块，用于接收基带信号，并对基带信号进行DPD处理产生DPD信号；基带信号处理模块，用于接收并将基带信号处理成目标基带信号，目标基带信号为经过窄带滤波的目标基带信号：DPD信号处理模块，用于接收并将DPD信号处理成目标DPD信号：合路器，用于将目标基带信号和目标DPD信号进行合路，产生合路信号；信号输出处理模块，用于输出合路信号。本发明专利技术实施例采用分别对基带信号和DPD信号进行处理，在合路之前提高了基带信号部分的信噪比，降低合路后的合路信号的发射噪声和发射杂散，在相同的射频发射杂散指标要求下，可采用更高的发射功率发射输出信号。

A DPD system and its implementation method

The invention provides a DPD system and a method for realizing the same. The system includes the DPD module, which receives the baseband signal and generates the DPD signal by DPD processing of the baseband signal; the baseband signal processing module is used to receive and process the baseband signal into the target baseband signal. The target baseband signal is the target baseband signal passing through the narrowband filter: the DPD signal processing module, which is used to receive and to DP the DP The D signal is processed into a target DPD signal: a circuit breaker, which is used to combine the target baseband signal with the target DPD signal to produce a road signal, and the signal output processing module is used to output the circuit signal. The embodiment of the invention adopts the processing of baseband signal and DPD signal separately, improves the signal to noise ratio of the baseband signal part before closing the road, reduces the emission noise and emission of the road signal after the closing, and can use the higher emitter emitter output signal under the same RF emission and spurious requirement.
