WLC28-2: A Simple IR-UWB Receiver Adapted to Multi-User Interferences

We propose in this paper a simple receiver adapted to multi user interferences (MUI) in impulse radio ultra wide band (IR-UWB). It is known that MUI distribution is not Gaussian in several cases. The classical correlation receiver which is adapted to Gaussian noise, is not adapted to the particular form of UWB MUI and is often far from the performance computed through the standard Gaussian approximation. We show that modeling MUI by a generalized Gaussian distribution helps in deriving a simple receiver which increases the performances and may also outperform the standard Gaussian approximation which was considered formerly to be too optimistic.
