Propagation Modeling for UWB Body Area Networks: Power Decay and Multi-Sensor Correlations

Body area networks are now accepted as an important part of 4th generation mobile technology. These networks operating at very low consumption, efficient power radio communications have to be developed. A promising solution is using multi-sensor MIMO (MS-MIMO) ultra-wideband (UWB) systems : each sensor carries one antenna, while the central device uses an antenna array. Thereby, This work proposes a new analytical channel model for the diffracted waves mechanism. This is derived from the existing IEEE 802.15.4 a standard channel model and innovates with space-time considerations.
