In this contribution we propose a simple codec for ultra wideband (UW) radio networks limited by multi-user interference (MUI). The proposed codec exhibits adaptive capabilities with respect to MUI degrading effects and, depending on MUI level, it may switch from a hard-detection operating mode to a soft-detection one. So doing, the presented scheme gains resistance against near-far effect. Several numerical tests show that our scheme outperforms conventional ones currently planned for UWB systems up to several orders of magnitude in MUI-limited wireless local area networks (WLANs).
