  Abstract

In this paper, we propose a detection scheme for ultra wideband (UWB) multiple access (MA) systems. The proposed detection scheme for weak signals is robust to the variation of impulsiveness which is the general characteristic of channel noise in UWB-MA environments. The proposed detection criterion has been designed in order that it can be equal to the optimum criterion for Gaussian (symmetric -stable (SαS) when α=2) noise, and also equal to the locally optimum (LO) criterion for Cauchy (SαS when α=1) noise. Numerical results show that the proposed detector has the same performance as the Gaussian-optimum (GO) detector in Gaussian channel, the same performance as the Cauchy-LO (CLO) detector in Cauchy channel, and better performance than the GO and CLO detector in S S channel with 0＜α＜1 and 1＜α＜2 when the signal is of small amplitude.
