Recent advances in wireless communication technologies have had a transfor- tive impact on society and have directly contributed to several economic and social aspects of daily life. Increasingly, the untethered exchange of information between devices is becoming a prime requirement for further progress, which is placing an ever greater demand on wireless bandwidth. The ultra wideband (UWB) system marks a major milestone in this progress. Since 2002, when the FCC allowed the unlicensed use of low-power, UWB radio signals in the 3. 1–10. 6GHz frequency band, there has been signi?cant synergistic advance in this technology at the c- cuits, architectural and communication systems levels. This technology allows for devices to communicate wirelessly, while coexisting with other users by ensuring that its power density is suf?ciently low so that it is perceived as noise to other users. UWB is expected to address existing needs for high data rate short-range c- munication applications between devices, such as computers and peripherals or consumer electronic devices. In the long term, it makes available spectrum to - periment with new signaling formats such as those based on very short pulses of radio-frequency (RF) energy. As such it represents an opportunity to design fun- mentally different wireless systems which rely on the bandwidth of the signals to enhance the data rate or which use the available bandwidth for diverse applications such as ranging and biomedical instrumentation.

Chipless RFID Reader Design for Ultra-Wideband Technology: Design, Realization and Characterization deals with the efficient design of Field Programmable Gate Array (FPGA) based embedded systems for chipless readers, providing a reading technique based on polarization diversity that is shown with the aim of reading cross-polarized, chipless tags independently from their orientation. This approach is valuable because it does not give any constraint at the tag design level. This book presents the state-of-the-art of chipless RFID systems, also providing useful comparisons. The international regulations that limit the UWB emission are taken into consideration, along with design guidance. Two designed, realized, and characterized reader prototypes are proposed. Sampling noise reduction, reading time, and cost effectiveness are also introduced and taken into consideration. - Presents the design, realization and characterization of chipless RFID readers - Provides concepts that are designed around a FPGA and its internal architecture, along with the phase of optimization - Covers the design of a novel pulse generator

This book covers the fundamental principles behind the design of ultra-low power radios and how they can form networks to facilitate a variety of applications within healthcare and environmental monitoring, since they may operate for years off a small battery or even harvest energy from the environment. These radios are distinct from conventional radios in that they must operate with very constrained resources and low overhead. This book provides a thorough discussion of the challenges associated with designing radios with such constrained resources, as well as fundamental design concepts and practical approaches to implementing working designs. Coverage includes integrated circuit design, timing and control considerations, fundamental theory behind low power and time domain operation, and network/communication protocol considerations.

Interest in indoor wireless communications has been increasing. In addition to high throughput WLAN systems such as 802.11a/b/g/n, attention is also being focused on lower rate, short distance systems such as Bluetooth and Zigbee. These low rate radios are being proposed for a variety of applications including automation/security, smart toys, remote sensing/control, asset tracking, and as a replacement for computer peripheral wires. While not demanding aggressive throughput, these radios do require low cost, power efficient operation and optionally the ability to perform ranging. Unfortunately, currently reported radios are up to an order of magnitude away from these power and cost targets or do not support ranging. However, a recent ruling from the FCC has opened up nearly 8GHz of unlicensed spectrum (from dc to 960MHz and from 3.1GHz to 10.6GHz) for ultra-wideband (UWB) deployment. One attractive method of UWB signaling that seems suited to a low power, highly integrated implementation communicates with short pulses, on the order of a nanosecond, that spread energy over at least 500MHz of bandwidth. Termed "impulse-UWB," the baseband nature of this signaling promises low cost and low power consumption through design simplicity, pulsed (or "duty-cycled") operation, and a "mostly-digital" implementation. The benefits of this approach are balanced by the risk of jamming from in-band interference, of stricter sampling and gain constraints, and of increased digital complexity. This dissertation presents the system exploration, specification, design, and demonstration of a low power, highly integrated, flexible, baseband, impulse ultra-wideband transceiver front-end.
