They are widely used in wireless communications, networking, radar, imaging, and positioning systems. In 2002, the Federal Communication Commission (FCC) legalized low power UWB emission between 3.1 GHz and 10.6 GHz for indoor communication devices stimulating many novel UWB applications such as personal area networks (PANs), accurate tracking and location, safety and homeland security. Since then, UWB technologies attracted a great research and practical interest. In recent years, UWB technologies have been rapidly developing. The number of scientific articles concerning different aspects of UWB technologies is enormous and hardly observable. For this reason, it is important to present to the UWB community an adequate review of novel UWB technology applications. We have tried our best in order to provide such a review in the proposed book Novel Applications of the UWB Technologies. The book is divided into five parts concerning the UWB communication systems, and UWB applications in PANs, medicine, radars and localization systems. Part 1, General Aspects of UWB Communication Systems, includes chapters 1 - 6 describing the general problems of UWB communication systems such as modulation formats, transmitter and receiver architecture, UWB communication system performance. Part 2, Novel UWB Applications in Networks, includes chapters 7 - 10 related to novel UWB applications in wireless personal area networks (WPANs), wireless sensor networks (WSNs), femtocells, and vehicles. Part 3, Novel UWB Applications in Cognitive Radio Systems, consists of chapters 11 - 13 where the problems of UWB cognitive radio are considered. Part 4, Novel UWB Applications in Medicine, includes chapters 14 - 16 where the novel UWB technology applications in medicine are presented. Finally, part 5, Novel UWB Application in Radars and Localization Systems, consists of chapters 17 - 20 and describes the UWB radar and localization problems. X Preface Consider briefly the outline of the chapters. In Chapter 1, the multiband orthogonal frequency division multiplexing (MB-OFDM) modulation and demodulation are considered. In order to optimize the UWB system performance the authors proposed a cost-effective and high performance modulation scheme based on quadrature phase shift keying (QPSK) and dual carrier modulation (DCM). In Chapter 2, the time hopping (TH)-UWB system model based on orthogonal pulse waveform is presented. The chapter contains a detailed analysis of the pulse based modulation schemes over multipath channel and power spectral density (PSD) for pulse shape modulation (PSM), bi-orthogonal PSM (BPSM), and combined modulation scheme of orthogonal pulse position modulation (OPPM)-BPSM. In Chapter 3, a fully integrated CMOS 6-9 GHz 9 bands transceiver for double carrier (DC) OFDM UWB system realized on the chip is described in detail. It is shown in particular that 9 carrier frequencies from 6336 MHz up to 8712 MHz with a frequency gap of 264 MHz are available. In Chapter 4, a novel simulation methodology of impulse radio (IR) UWB energy detection receiver has been developed. In Chapter 5, the correlation properties of the time-hopping (TH) sequences for TH spread spectrum (THSS) UWB systems are analyzed. The theory of TH sequences is developed and a method to improve TH sequences correlation properties is proposed. In Chapter 6, the problem of UWB system performance in single-user and multi-user environments is discussed. A fine synchronization algorithm for pulse amplitude modulation (PAM) and pulse position modulation (PPM) UWB signals with a spread spectrum involving TH is proposed. In Chapter 7, a comprehensive review of the latest developments in the field of high- speed WPANs is provided. UWB technology is especially promising for WPAN applications due to high bandwidth and small communication ranges. In Chapter 8, the UWB technology applications in WSNs are analyzed. UWB technology manifests high robustness to interference and provides low complexity and low energy consumption receivers and transmitters for WSNs. In Chapter 9, a novel concept of the fourth generation femtocell is proposed. The system is based on a recently developed UWB-radio-over-optical-fiber (UROOF) technology. It is characterized as a green femtocell since its energy consumption is significantly lower as compared to wireless systems. In Chapter 10, a novel interesting application of UWB technology is described that combines the advantages of the low cost radio-over-fiber (RoF) links and wireless [...]... the effect of the UWB interference on the next generation weather radar has been investigated Different scenarios have been discussed concerning the UWB antenna configurations and the environment influence on the UWB system performance In Chapter 19, the UWB system applications in indoor ranging/localization are reviewed A novel algorithm for the time -of- arrival (ToA) estimation is developed, and the. .. carriers each set at either end of the IFFT input data set, and they are the same values as the 5 neighbouring data subcarriers The power can be reduced on the guard subcarriers with the objective to relax the specifications of the analogue transmit and receive filters The guard subcarriers can be considered as another form of time and frequency diversity, at least to the 2 sets of 5 neighbouring data... What is of upmost interest is to apply the CSI as a demapping technique for the MB-OFDM system at the higher data rates, where the DCM modulation scheme is used Softbitm Rm CSI k (20) where m is the index of the numbers of soft bit value depending on the modulation scheme; k is the index into the 100 data subcarriers in an OFDM symbol CSI Modified Soft Bits Soft Bit Modifier Rm Fig 16 Demodulation... in which the band is hopped by using a Time-Frequency code (TFC) known to both transmitter and receiver The transceiver transmits a single OFDM symbol in one band, and then the next transmitted OFDM symbol is hopped to the next band Figure 4 depicts OFDM symbols transmitted in RF signal 6 Novel Applications of the UWB Technologies utilizing a TFC within Band group 1 (BG1) There are two types of TFCs:... repetition of the same information (complex number) mapping over the OFDM symbols for the slowest 5 out of the 8 coding schemes In conjunction with the FDS approach, 50 QPSK symbols and 50 of their respective conjugate values are mapped onto 100 OFDM data subcarriers as conjugate symmetric IFFT inputs As a result, the transmitter only needs to implement the real portion of the IFFT output As for the TDS... the soft bit trackback memory to search the 64 trellis states for each information bit The soft-QPSK demapping process can improve WPAN receiver performance where each input complex number for the demapper outputs two soft bits being the symbol likelihood The demapping process can be simply the process of outputting real part (I value) and then the imaginary part (Q value) of the input symbol for the. .. in detail The UWB systems for the 3D localization, the research systems, the aspects of the microwave radiation interaction with biological tissues, and state -of- the- art in wireless medical systems are discussed Novel experimental results for electromagnetic interference in the operating room are presented In Chapter 15, the experimental aspects of the breast cancer detection based on the UWB imaging... obtained from the multiplication of the demodulation soft output Rm and its corresponding CSIk, as described in (20) The receiver is arranged to modify the soft bits using the CSI, as illustrated in Figure 16 The overall data reliability is obtained from directly scaling the soft bit value by the corresponding CSI value Therefore the reliability of received data is maximized What is of upmost interest... within the configuration of the current standard increasing system throughput thus maintaining the high rate throughput even with a moderate level of dropped packets 2 MB-OFDM in ECMA-368 2.1 UWB standardization The fundamental issue of UWB is that the transmitted signal can be spread over an extremely large bandwidth with very low Power Spectral Density (PSD) In early 2002, the 4 Novel Applications of the. .. estimation is in the presence of thermal noise offering better decoding result The LS algorithm having low complexity to implement is one of the popular methods for the OFDM based system channel estimation 16 Novel Applications of the UWB Technologies without using any knowledge of the statistics for the channels, as in (17) Furthermore, it has been shown that LS estimation has similar performance close .
