  Abstract

In this paper we proposed system parameter values of ultra-wideband Impulse Radio systems for the frequency band(3.1～10.6GHz), which is allocated by Federal Communications Commission(FCC). We also analyzed performance of the proposed system in the multiple access interference environment.
According to result, application of possible pulse duration(tn) is very limited by 0.04～0.0326 ns in permission frequency range that establish in FCC. In the case of the same pulse signal power, we could know that system performance was changed by pulse repetition number(Ns) regardless of pulse duration. Thus, We could know that we have to need duration of monocycle pulse and setting of frame unit time(Tf) according to multi user numbers and design proper pulse repetition number by transfer rate in multiple access systems design. In the IR system that needs high speed transmission more than 50 Mbps in multiple access interference environment, we could know that very serious performance decrease by multiple access interference happens. Therefore, as the design of high speed multiple access IR system, it should be designed to additional improvement techniques that can remove multiple access interference at the same time.
