Summary: 
In this letter, we consider a diversity precoding scheme for signal detection in ultra-wideband (UWB) multiple input single output (MISO) systems, which consists of linear diversity prefilters in the transmitter. For a UWB MISO system, the BER performance of a linear transmit diversity precoding system with imperfect channel estimation is presented in IEEE 802.15.3a UWB multipath channels and also compared with that of a linear receive diversity postcoding approach. It is shown that the diversity precoding UWB MISO system offers the performance equivalent to the diversity postcoding scheme for single input multiple output (SIMO) systems while making the mobiles low-cost and low-power.
