Directional analysis of the on-body propagation channels considering human's anatomical variations

This paper presents a directional analysis of the on-body propagation channels using the high resolution space alternating generalized expectation (SAGE) maximization algorithm. The analysis has been done on data obtained through FDTD simulations, on a male and a female numerical phantom. For estimating the angle of arrival (AoA) at a four element square array located at the chest, two different positions of the transmitter are considered. The presented results show that the anatomical variations between a male and a female results in different AoA for the same position of the transmitter-receiver pair. Directional analysis of the on-body channels could be used for increasing the reliability of the communication link between on-body devices.
