Wireless sensor network based on UWB technology

Ultra-wideband (UWB) is suitable for low complexity and short communication distance and low average transmit power. In this paper, combining UWB technology characteristic, UWB sensor network advantage is introduced. This UWB system is based on an energy detection receiver associated with a simple transmitter based impulse generation. A new coding method TFS isproposed, which can result in very simple CMOS implementation in a low data rate sensor network.
