Compensation of Transmitter Distortion Using a Nonlinear Modeling Approach

• In this paper, a nonlinear modeling approach is used to demonstrate a joint compensation scheme for the linear and nonlinear distortions in the I/Q modulator and the power amplifier. Based on this nonlinear model, a digital pre-compensator is constructed. The effects of these two mostdominant nonlinear components in a modern transmitter cantherefore be digitally pre-compensated in a single step. The results are verified by experiments, and the proposed approach shows promising performance.
