Abstract
This paper introduces a Single car-
rier Ultra-wideband (SC-UWB) transmission scheme with
Mean square error (MSE) channel estimation. Speci¯cally,
the scheme employs Direct sequence Binary phase shift
keying (DS-BPSK) to support high to moderate data rate
applications which di®erentiates from Multi-band Orthog-
onal frequency division multiplexing (MB-OFDM) and Im-
pulse radio (IR) UWB systems. Simulation results show
that, with baseband time-frequency signal processing al-
gorithms, the Bit error rate (BER) performance of the
SC-UWB system over the IEEE 802.15.3a UWB Chan-
nel model III (CM3) is about 10¡5 at Eb=N0 of 10.5dB.
Moreover, the SC-UWB system exhibits a low power con-
sumption and low implementation complexity due to its
low Peak-to-average ratio (PAR) and modulation charac-
teristics. It is evident that the scheme will be a good can-
didate for short range communications, especially for low
power and low cost applications such as mobile terminals.
