  • Abstract
    We show that one can do away with the cyclic prefix (CP) for SC-FDE and OFDM at the cost of a moderate increase in complexity of a DFT-based receiver. Such an approach effectively deals with the decrease in the number of channel uses due to the introduction of the CP. It is shown that the SINR for SC-FDE remains the same asymptotically with the proposed receiver without CP as that of the conventional receiver with CP
