In this report, a novel predistorter structure with a feedback configuration is proposed. It consists of a look-up-table in the forward path to deal with the static nonlinearity and a memory polynomial block in the feedback path to compensate memory effects. Since it is the inverse structure of memory polynomial, it can completely compensate the nonlinearity if the power amplifier is accurately modeled by the memory polynomial. Simulation results show that it can substantially suppress spectral regrowth caused by the amplifier with memory effects when compared to the well-established memory polynomial predistorter. |
