Book Description
Ultra wideband (UWB) interference on narrowband systems is a serious problem, which impedes the use and development of the UWB short range wireless communication technology. The UWB pulsed signal can degrade or block signals of narrowband systems that may exist in its transmission zone. Limited solutions have so far been proposed by different researchers to mitigate the UWB interference on specific narrowband systems at the cost of UWB system performance and increased complexity. This thesis proposes a novel technique to generate UWB pulses based on an effective way of shaping a continuous sine wave rather than using one of the conventional pulses of Gaussian family. Two pulse generators for narrowband interference mitigation have been designed and implemented. A proposed technique of pulse position phase modulation (PPPM) has been validated with the proposed pulse generators as a method to double the throughput speed. It has also been demonstrated that the proposed pulse generators can support a variety of modulation and transmission techniques with different throughput speeds and interference mitigation levels.Both pulse generators comply with the Federal Communications Commission (FCC) spectrum emission indoor and outdoor masks. The first generates shaped monocycle sine wave (SM-S) pulses and the second generates shaped monocycle half wave rectified sine wave (SM-HRS) pulses. The SM-S and SM-HRS pulse generators have minimum throughputs of 550 Mbps and 500 Mbps respectively using on-off keying (OOK) modulation. The interference mitigation level with the SM-HRS pulse generator achieved -90 dBm/MHz over 0-5.5 GHz range, which is so far better than any existing mitigation level. The SM-S pulse generator on the other hand, achieved less than -70 dBm/MHz over 0-5 GHz range, which is also high by comparison with the highest values achieved by other existing solutions. Both generators avoid interference with most existing narrowband systems including GPS, PCS, WiMAX, WLAN 802.11b and 802.11a.

Book Description
ULTRA WIDEBAND WIRELESS COMMUNICATION AN INTERNATIONAL PANEL OF EXPERTS PROVIDE MAJOR RESEARCH ISSUES AND A SELF-CONTAINED, RAPID INTRODUCTION TO THE THEORY AND APPLICATION OF UWB This book delivers end-to-end coverage of recent advances in both the theory and practical design of ultra wideband (UWB) communication networks. Contributions offer a worldwide perspective on new and emerging applications, including WPAN, sensor and ad hoc networks, wireless telemetry, and telemedicine. The book explores issues related to the physical layer, medium access layer, and networking layer. Following an introductory chapter, the book explores three core areas: Analysis of physical layer and technology issues System design elements, including channel modeling, coexistence, and interference mitigation and control Review of MAC and network layer issues, up to the application Case studies present examples such as network and transceiver design, assisting the reader in understanding the application of theory to real-world tasks. Ultra Wideband Wireless Communication enables technical professionals, graduate students, engineers, scientists, and academic and professional researchers in mobile and wireless communications to become conversant with the latest theory and applications by offering a survey of all important topics in the field. It also serves as an advanced mathematical treatise; however, the book is organized to allow non-technical readers to bypass the mathematical treatments and still gain an excellent understanding of both theory and practice.

Book Description
Ultra wide band (UWB) is an extremely promising wireless technology for researchers and industrials. One of the most interesting is its high data rate and fading robustness due to selective frequency fading. However, beside such advantages, UWB system performance is highly affected by existing narrowband interference (NBI), undesired UWB signals and tone/multi-tone noises. For this reason, research about NBI cancellation is still a challenge to improve the system performance vs. receiver complexity, power consumption, linearity, etc. In this work, the two major receiver sections, i.e., analog (radiofrequency or RF) and digital (digital signal processing or DSP), were considered and new techniques proposed to reduce circuit complexity and power consumption, while improving signal parameters. In the RF section, different multiband UWB low-noise amplifier key design parameters were investigated like circuit configuration, input matching and desired/undesired frequency band filtering, highlighting the most suitable filtering package for efficient UWB NBI cancellation. In the DSP section, due to pulse transmitter signals, different issues like modulation type and level, pulse variety, shape and color noise/tone noise assumptions, were addressed for efficient NBI cancelation. A comparison was performed in terms of bit-error rate, signal-to-interference ratio, signal-to-noise ratio, and channel capacity to highlight the most suitable parameters for efficient DSP design. The optimum number of filters that allows the filter bandwidth to be reduced by following the required low sampling rate and thus improving the system bit error rate was also investigated.

Book Description
Advanced concepts for wireless technologies present a vision of technology that is embedded in our surroundings and practically invisible. From established radio techniques like GSM, 802.11 or Bluetooth to more emerging technologies, such as Ultra Wide Band and smart dust motes, a common denominator for future progress is the underlying integrated circuit technology. Wireless Technologies responds to the explosive growth of standard cellular radios and radically different wireless applications by presenting new architectural and circuit solutions engineers can use to solve modern design problems. This reference addresses state-of-the art CMOS design in the context of emerging wireless applications, including 3G/4G cellular telephony, wireless sensor networks, and wireless medical application. Written by top international experts specializing in both the IC industry and academia, this carefully edited work uncovers new design opportunities in body area networks, medical implants, satellite communications, automobile radar detection, and wearable electronics. The book is divided into three sections: wireless system perspectives, chip architecture and implementation issues, and devices and technologies used to fabricate wireless integrated circuits. Contributors address key issues in the development of future silicon-based systems, such as scale of integration, ultra-low power dissipation, and the integration of heterogeneous circuit design style and processes onto one substrate. Wireless sensor network systems are now being applied in critical applications in commerce, healthcare, and security. This reference, which contains 25 practical and scientifically rigorous articles, provides the knowledge communications engineers need to design innovative methodologies at the circuit and system level.
