Abstract
In this study, we carry out theoretical analysis combined with computer simulations for performance comparisons between uncoded orthogonal frequency division multiplexing (OFDM) and single-carrier frequency-domain equalization (SC-FDE) systems on frequency-selective static channels as well as frequency-selective fading channels. We consider both zero-forcing and minimum mean square error equalizations for data detection. Theoretical evaluations for output signal-to-noise ratio and error rate performance are presented for both OFDM and SC-FDE systems. Then, error rate bounds for both systems are derived. Combining all the analytical results with computer simulations, we reach certain important conclusions on the superiority between OFDM and SC-FDE systems.
