高效DPD算法在无线基站设备中，末级功率放大器的失真是影响无线带宽的主要因素之一。当前业界的主流解决方案是采用数字预失真技术，在下行信号中加入失真补偿分量以对消PA输出的失真成分，达到提升带宽的目的。(The distortion of the amplifier is one of the main factors that affect the wireless bandwidth. The mainstream solution of the industry is to use digital pre distortion technology, in the downlink signal to join the distortion compensation component to eliminate the distortion of the PA output components, to achieve the purpose of improving the bandwidth.)
