Abstract:
This paper intends to study the nonlinearity of LTE RF power amplifier and compensate for nonlinearity and memory effect of the amplifier, and compare the digital pre-distortion lookup table-based Digital pre-distortion and memory polynomial pre-compensation effect of the device. It can draw a conclusion that Digital Pre-Distortion can improve ACLR well, the memory effect of the amplifier in the single-carrier FDD-LTE signals can also be compensated at a certain degree. © 2013 Springer-Verlag.
