Abstract :
In this study, multiple-input multiple-output (MIMO) techniques are applied to single-carrier (SC) frequency domain equalization (FDE) Ultra-wide band (UWB) systems with blockwise processing to obtain both frequency diversities and spatial diversities, for very high data transmission, over strongly frequency-selective UWB channels. Time reversal space-time block coding (TR-STBC) is utilized to achieve transmit diversity in the proposed scheme. The receiver employs Minimum mean-squared error (MMSE) FDE scheme and zero-forcing (ZF) FDE scheme with equal gain combining (EGC) diversity, respectively, to overcome the fading effect of UWB channels. Furthermore, this study presents a theoretical performance analysis result on conditional bit error rate (BER) in terms of various antennas numbers and different equalization schemes. Simulations are also provided for demonstrating that the proposed MIMO transceiver scheme for SC-FDE UWB preponderates over the SISO scheme and the oversampling diversity case.
