Abstract
This paper implements differential space-time-frequency codes (DSTFCS) to multipleinput multiple-output (MIMO), multi-band impulse radio ultra-wideband (MB-IR-UWB) system. Four scenarios of the system operating mode have been put forward and combination of DSTFCs and the system has been studied in this paper. Through simulation, a comparison of BER performance among different scenarios and channel statements is analyzed. In addition, considered inter-symbol interference (ISI), the simulation on system with ISI and without ISI is given. Finally the conclusion that scenario 3 is more suitable to the proposed MIMO MB-IR-UWB system for it being less sensitive to ISI has been drawn.
