ABSTRACT
This work analyzes the impact of delay spread on IEEE 802.15.4a networks using energy detection (ED) receivers.Specifically, we review the typical values for delay spread in Ultra Wide Band (UWB) systems reported to date forindoor, outdoor and industrial environments, and study how the delay spread impacts the bit-error rate with andwithout Multiuser Interference (MUI).
