• BICM-OFDM-non linear-distortions

Wireless networks has necessarily
to take into account the degradation effects induced by nonlinear power amplification. The aim of this thesis
is to develop an analytical framework for the theoretical characterization and performance evaluation of a
BICM-OFDM with AMC in presence of nonlinear distortions. The accurate description of
several system features is enabled through the application of the specific version of the
Bussgang theorem extended to bandpass memoryless nonlinearities with complex Gaussian nonzero-mean
non-stationary inputs. Extensive simulation results successfully verify the accuracy of the proposed analysis
under operating conditions, thereby demonstrating the effectiveness in improving
the computational efficiency of conventional simulation-based-only performance evaluation procedures.
