In this paper, we present the space time block codes (STBC) based M-ary code-selected modulation scheme of direct sequence bipolar pulse amplitude modulation (DSBPAM) ultra wideband (UWB) system with selective Rake (SRake) receiver and maximum ratio combining (MRC) over multipath channels in order to improve the system performance and transmission rate of the conventional DS UWB system. The system bit error probability is derived and the signal processing algorithm is provided. Simulation is performed with different SRake receiver fingers over multipath channels. The results show the efficiency of the M-ary STBC based DS-BPAM UWB scheme in both system performance and transmission rate.
