BER analysis of filter-bank multicarrier with offset quadrature amplitude modulation systems with phase estimation error

This study analyses the bit-error-rate (BER) performance of filter bank multicarrier (FBMC) systems with offset quadrature amplitude modulation in the presence of phase offset. The authors consider that the FBMC intrinsic-interference has a Gaussian probability distribution, and they derive the BER analytical expressions for multilevel modulation over Rayleigh flat fading channels. Analytical expressions developed in this study are checked and confirmed by computer simulations.
