Cyclic prefixed single carrier transmission in ultra-wideband communications

This paper investigates the performance of cyclic prefixed single carrier with frequency domain equalization (SC-FDE) transmission over the ultra-wideband (UWB) propagation environment. The performance of SC-FDE over IEEE 802.153a UWB channel models is analyzed, simulated and compared with that of impulse based single carrier UWB (SC-UWB) and multicarrier UWB (MC-UWB) employing orthogonal frequency-division-multiplexing (OFDM). The impact of channel coding with different code rates on the performance of OFDM and SC-FDE in UWB is also studied. Our results demonstrate conclusive performance advantage of the SC-FDE scheme, especially when implementation issues such as low complexity and low power consumption for UWB are taken into account.
