Summary of Technical Doctoral thesis: Nonlinear distortions and countermeasures for performance improvements in contemporary radio communication systems

Evaluating nonlinear HPA models regarding to problem of simulating intermodulation products (IMP). Proposing the polysine model for precise simulation of IMPs, especially for signals with complex structures. Proposing the use of predistortion schemes for MIMO-STBC systems based on thorough analyses of the nonlinear HPA effects on these systems with transmit/receive filters introduced in the model.

A thesis for the degree of Doctor of Philosophy: Nonlinear distortions and countermeasures for performance improvements in contemporary radio communication systems

Study counter measures to limit the adverse impacts of nonlinear distortions in MIMO-STBC systems using predistortion at the transmitter; propose phase estimation and compensation schemes that overcome the adverse impacts of nonlinear distortions at the receiver.
