Design and implementation of a simulator for wireless communication nonlinear distortion

  • The non-linear distortion should be considered in aeronautics and astronautics communication applications due to high spectrum utilization and power efficiency. Numerous studies have been carried out on the non-linear distortion modeling and linearization of power amplifier. A design of nonlinear distortion simulator was presented. The simulator can be used in testing on anti-aliasing capabilities of wireless communication, testing on adaptive pre-distortion performance and providing specified amplifier conditions of communication systems. The coordinate rotation digital computer(CORDIC) pipeline and look-up-table (LUT) structure were utilized to realize the AM-AM and AM-PM conversion of amplifier in digital signal processing devices inside the emulator. Simulation and experiment results demonstrate the validity and feasibility of the design.
