An All-Digital Transmitter for Pulsed Ultra-Wideband Communication
Applications like sensor networks, medical monitoring, and asset tracking have led to a demand for energy-efficient and low-cost wireless transceivers. These types of applications typically require low effective data rates, thus providing an opportunity to employ simple modulation schemes and aggressive duty-cycling. Due to their inherently duty-cycled nature, pulse-based Ultra-Wideband (UWB) s...
متن کاملArchitecture of a Modular IEEE 802.15.4a Ultra-Wideband Transmitter
As part of a multi-channel, multi-band evaluation platform for future wireless sensor network applications, an IEEE 802.15.4a standard conform transmitter is investigated. The paper gives an overview of our transmitter concept and ultra-wide band signals according to IEEE 802.15.4a. It analyzes the system design aspects of the transmitter for high flexibility such as modularity and independency...
متن کاملUltra-WideBand Transmitter for Wireless Body Area Networks
The successful realization of a Wireless Body Area Network (WBAN) requires innovative solutions to meet the energy consumption budget of the autonomous sensor nodes. The radio interface is a major challenge, since its power consumption must be reduced below 100μW (energy scavenging limit). The emerging Ultra-WideBand (UWB) technology shows strong advantages in reaching this target. First, most ...
متن کاملDesign of a transmitter for Ultra Wideband Radio
Ultra Wideband Radio (UWB) is an upcoming alternative for wireless communications. Since the Federal Communication Commission in the USA allowed UWB for unlicensed usage in April 2002, more and more companies have started developing UWB systems. The major difference with UWB compared to other RF systems is that UWB sends information with pulses instead of using a carrier wave. The technique is ...
متن کاملA New Transmitted Reference Pulse Cluster Based Ultra-Wideband Transmitter Design
An energy efficient ultra-wideband (UWB) transmitter based on the novel transmitted reference pulse cluster (TRPC) modulation scheme is presented. The TRPC-UWB transmitter integrates, namely, wideband active baluns, wideband I-Q modulator based up-conversion mixer, and differential to single-ended converter. The integrated circuits of TRPC-UWB front end is designed and implemented in the 130-nm...
