Frequency-domain equalization of mobile radio and terrestrial broadcast channels

For mobile radio and terrestrial broadcast applications, we compare orthogonal frequency-division multiplexing (OFDM) and single-carrier transmission with frequency-domain equalization. With respect to our earlier results, we include channel coding and frequency-domain interleaving which are necessary for OFDM systems on multipath fading channels characterized by deep notches in the signal spectrum. Our results indicate that a single-carrier system with a frequency-domain equalizer achieves similar performance to coded-OFDM, while alleviating the carrier synchronization and nonlinear distortion problems inherent to this technique
