The human body is an extremely challenging environment for the operation of wireless communications systems, not least because of the complex antenna-body electromagnetic interaction effects which can occur. This is further compounded by the impact of movement and the propagation characteristics of the local environment which all have an effect upon body centric communications channels. As the ...

Next generation in-to-out-of body biomedical applications have adopted optical wireless communications (OWCs). However, by delving into the published literature, a gap is recognized in modeling channel, since most contributions neglect particularities of different types tissues. In this paper, we present novel pathloss and scattering models for OWC links. Specifically, derive extract analytical...

SHORT COMMUNICATIONS

In wireless body-centric communications, either the transmitter or the receiver, or both are located in close proximity to the human body. Thus, the Line-of-Sight (LOS) components of the radio signal are particularly susceptible to shadowing caused by human body. In earlier, the effect of human body shadowing was studied using κ-μ fading channel, where the resultant dominant signal components d...
