  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 the 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. The results are shown for $N_t$ transmit
antennas and $N_r$ receive antennas where $N_r \geq N_t$.
