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 for indoor, outdoor and industrial environments, and study how the delay spread impacts the bit–error rate with and without Multiuser Interference (MUI).

Keywords: IEEE 802.15.4a, delay spread, energy detection (ED), impulse radio ultra wide band (IR–UWB), multiuser interference (MUI).

 

RESUMEN

En este trabajo se analiza el impacto del esparcimiento del retardo en redes IEEE 802.15.4a con receptor detector de energía (ED). Específicamente, se hace una revisión de los valores típicos del esparcimiento del retardo en las transmisiones de banda ultra ancha (UWB) reportados hasta la fecha en escenarios de interiores, exteriores e industriales, y además se estudia cómo el esparcimiento de retardo impacta la tasa de error de bit con y sin interferencia multiusuario (MUI).
