Abstract

In this paper, we analyze and simulate performance of space time block coded (STBC) binary pulse amplitude modulation-direct sequence (BPAM-DS) ultra-wideband (UWB) systems with double binary turbo code in indoor environments. The indoor wireless channel is modeled as a modified Saleh and Valenzuela (SV) channel, which is proposed as a UWB indoor channel model by IEEE 802.15.SG3a. From simulation results, it is shown that the STBC scheme does not have an influence on improving bit error probability performance of the PAM-DS UWB systems. It is also shown that the double binary turbo coding scheme offers considerable coding gain compared with an uncoded system according as the number of iterations increases.
