- Abstract
- (en) A new kind of wireless personal and body-centric network has emerged for a few years. It is composed of several sensors placed on the human body and measuring vital information. This information is then carried out towards a central body-worn device. This wireless network is known as a Body Area Network. Several applications are foreseen, e.g. patient monitoring, where the user is no longer restricted to one specific place and can be taken care of remotely. In this work, multi-sensor (MS) multiple-input multiple-output (MIMO) systems with ultra-wideband (UWB) transmissions are proposed in order to reduce the energy consumption at each sensor in the BAN. Each sensor consists of one antenna while the central device (where most of the computational complexity is located) uses an antenna array. Yet, the development of efficient space-time algorithms requires a full UWB MS-MIMO channel characterization, with a special attention to both spatial and delay domains. In what follows, a new channel modeling for wireless communication around the body is presented. Especially, the body propagation mechanisms are emphasized.
