摘　　要：This paper introduces a Single carrier Ultra-wideband （SC-UWB） transmission scheme with Mean square error （MSE） channel estimation. Specifically,the scheme employs Direct sequence Binary phase shift keying （DS-BPSK） to support high to moderate data rate applications which differentiates from Multi-band Orthogonal frequency division multiplexing （MB-OFDM） and Impulse radio （IR） UWB systems. Simulation results show that, with baseband time-frequency signal processing algorithms, the Bit error rate （BER） performance of the SC-UWB system over the IEEE 802.15.3a UWB Channel model III （CM3） is about 10-5 at Eb/No of 10.5dB. Moreover, the SC-UWB system exhibits a low power consumption and low implementation complexity due to its low Peak-to-average ratio （PAR） and modulation characteristics. It is evident that the scheme will he a good candidate for short range communications, especially for low power and low cost applications such as mobile terminals.
