Mathematical modeling of ultra wideband in vivo radio channel [PDF]
, 2018 This paper proposes a novel mathematical model for an in vivo radio channel at ultra-wideband frequencies (3.1–10.6 GHz), which can be used as a reference model for in vivo channel response without performing intensive experiments or simulations.
