Abstract
In this paper, a memory polynomial nonlinear model-based pre-distorter is utilized to linearize a wideband RF power amplifier for a TD-LTE system. The nonlinear model is briefly introduced and frame structure of the TD-LTE signal has been described in detail. In addition, the compensation results of nonlinear distortions for the TD-LTE signal are presented, which illustrated that the memory polynomial model-based pre-distorter exhibits good performance in suppressing the spectrum re-growth caused by the memory effects of the wideband power amplifier.
