dc.description.abstractIn this paper, we consider two reducedPMEPR (Peak to Mean Envelope Power Ratio) CPassisted (Cyclic Prefix) block transmission alternatives, having in mind an application to the uplink of future mobile broadband systems: clipped (and filtered) OFDM (Orthogonal Frequency Division Multiplexing) and SC/FDE (Single Carrier/Frequency-Domain Equalization). In both cases, we adopt advanced receivers with space diversity and a similar structure, where an iterative cancellation of unavoidable interferences is carried out: deliberate nonlinear interference, in the Clipped-OFDM case; residual linear ISI, in the SC/FDE case. Performance results are reported and discussed, with the help of selected performance bounds, thereby providing relevant ”SC vs OFDM” comparisons. A clear advantage for the SC/FDE side is shown to exist when a 4-QAM (Quadrature Amplitude Modulation) constellation is selected in both cases. When the constellation size is increased, the SC/FDE advantage decreases, namely when the clipping effort is strong enough to reduce the OFDM PMEPR to a level below that of the corresponding SC/FDE scheme.pt_PT
