Influence of Channel Frequency Selectivity and Modulation Order on the Performance Difference Between DFE-SCCP and OFDM

This article provides a performance comparison between the orthogonal frequency division multiplexing (OFDM) and the single-carrier with cyclic prefix with a decision feedback equalizer (DFE-SCCP) through a channel capacity analysis. A semi-analyticalapproachtotheproblemispresentedandtheyare assessed by simulation results for different modulations, channels and coding rates.
