Abstract

In this paper, we present a space time block coded (STBC) MIMO-OFDM scheme for indoor UWB using whose channel is frequency selective because of full of multipaths. After briefly introducing transmit diversity of MIMO-OFDM, we give out STBC scheme which can achieve space and frequency diversity gain. Numerical simulation results show that in the UWB environment, the performance of the STBC MIMO-OFDM system proposed in this paper is improved compared with conventional space frequency block coded OFDM systems.
