Statistical Modeling of Ultrawideband Body-Centric Wireless Channels Considering Room Volume

الملخص EN

This paper presents the results of a statistical modeling of onbody ultrawideband (UWB) radio channels for wireless body area network (WBAN) applications.

Measurements were conducted in five different rooms.

A measured delay profile can be divided into two domains; in the first domain (04 ns) has multipath components that are dominant and dependent on room volume.

The first domain was modeled with a conventional power decay law model, and the second domain with a modified Saleh-Valenzuela model considering the room volume.

Realizations of the impulse responses are presented based on the composite model and compared with the measured average power delay profiles.
