Combination aspects of low and high data rate ultra-wideband devices

This paper proposes a combined UWB LDR-LT/HDR structure and cooperation possibilities between both systems. A possible structure that utilizes the LDR physical layer to transmit and receive the HDR signaling information for an improved system performance with reduced power consumption is investigated. In addition, an adaption layer is proposed which organizes the cooperation between the two systems by following newly developed protocols. The system performance of the combined system is discussed as well.
