Monte-Carlo estimation of time mismatch effect in an OFDM EER architecture

New 5 GHz wireless local area networks standards use OFDM modulation in order to increase data rate transfer. An OFDM transmitter needs a linearization technique due to nonlinearities of the power amplification operation. The EER architecture can be used to solve this problem while keeping high efficiency. However several sources of imperfections lower the quality of the signal. Time mismatch has especially a great impact on EVM and spectral re-growths. This work presents a Monte Carlo study of envelope/phase delay influence on the OFDM signal. The autocorrelation is estimated considering the OFDM signal as complex Gaussian.
