Abstract :
This paper presents an experimental investigation into the in-body channel in 400 MHz MICS Band. By taking into account the joint effect of human movement and multipath effects, the measurements have been conducted in a populated office at very short distances. The dynamic channel behaviour has been captured and based on the statistical analyses of fading duration, a six-state Semi-Markov model that considers both Line of Sight (LOS) and Non Line of Sight (NLOS) cases is proposed. Parameters of the Semi-Markov model are estimated from the measured data. The validity of this model is confirmed by comparison of the first order and second order statistics of the proposed model with the measured data.
