The level of interference caused by Ultra-Wideband (UWB) systems in current radio services has been widely studied, both theoretically and with measurement campaigns, although most of them focus on pulse-based UWB systems. This paper presents experimental results on the coexistence of Multiband Orthogonal Frequency Division Multiplexing (MB-OFDM) UWB systems when they are working in close proximity to other radio technologies such as UMTS, WiMAX, LTE, WiFi, Bluetooth and ZigBee. As restrictive spectrum masks have been imposed to UWB, no degradation is detected on those systems except for WiMAX as it operates in the same frequency band. On the other hand, MB-OFDM may be disturbed even by systems operating in a different frequency band due to spurious out-of-band emissions. The coexistence between MB-OFDM and Impulse Radio (IR) UWB systems is also addressed and experimental results are presented showing that IR UWB may interfere with MB-OFDM UWB systems causing a degradation on Packet Error Rate, which is limited due to the low activity factor of IR UWB.

Impulse-radio UWB (IR-UWB) transceivers are quite interesting since they can achieve high data rate while consuming low power. But UNII Band interferers are a serious problem for using the whole spectrum in IR-UWB. Also the short range of UWB is a serious limitation to this technology. Here we have proposed a solution to overcome both of the above mentioned problems. Matched filter concept shapes the output noise according to its spectrum so it can act as a noise filter. Matched filter is implemented in analog domain by designing an all optical UWB pulse featuring notches that can be tuned to a certain frequency. Therefore, any narrowband interferer can be nulled out passing through the matched filter. Also no transmission is done in the spectrum of the narrow band system so no interference is caused by UWB system. On the other hand since the pulse is implemented fully optically, by using UWB over fiber, the UWB range can be greatly extended. Modified Hermite polynomials have unique properties which are used for designing an optical UWB pulse with frequency nulls in its spectrum. For optical implementation of the proposed UWB pulse, Gaussian laser beams are combined to provide a signal with similar properties of Modified Hermite polynomials. The proposed system consists of a single wave length laser source, optical delay, power splitter/combiner, a length of single mode fiber (SMF) and a photo detector (APD). The simulation results shows that for short range communication the proposed architecture can tolerate large in band interferers up to 30 dBm. For long range the tolerance is degraded to 0dBm interferer power which is still quite high.

This work presents the advantages and capabilities of the UWB beamforming RF architecture introduced in [1]. The proposed system gathers the functionalities of high ranging accuracy and angle of arrival (AOA) techniques. In addition, the system has been designed to dissipate low power. This performance is achieved thanks to a double quadrature receiver. Ranging simulation shows a 1.1cm standard deviation at 6m range using a 15.6MHz pulse repetition frequency (PRF). This accuracy can be extended to 20m range by using a 1.5MHz PRF. Otherwise, at 6m, AOA has been estimated to have a root mean square error (RMSE) lower than 1° in the ±50° aperture. The simulation results prove that this architecture is robust against channel noise and RF impairments.

The regulatory agencies in Europe and Japan require the implementation of avoidance techniques in some bands to reduce interference to licensed systems. Accordingly, ultra-wideband impulse radio (UWB-IR) based Wireless Personal Area Network (WPAN) standard IEEE 802.15.4a has suggested using linear combination of pulses to reduce interference to coexisting primary systems. In this paper, we consider the implementation of linear combination of pulses for a peaceful coexistence, and assess the UWB-IR system performance in the presence of an active narrowband system. For that, we study the possible transmitter and receiver structures that can be adapted for the physical layer of the IEEE 802.15.4a standard. The study shows that while the bit-error rate (BER) performances of coherent and noncoherent receiving structures may be slightly degraded with the use of linear combination of pulses when there is no active primary system, the performances can be significantly improved with appropriate filtering techniques at the receiver when the primary system is active.

When a UWB signal is transmitted, we expect there to be a number of reflected multipath signals because of reflections due to objects in the environment. As a result of these reflected signals, it is impossible to define the ellipses that would be used for target detection as described by existing elliptical based localization schemes when we consider a highly multipath rich environment such as a typical UWB propagation channel unless we are able to manipulate the multipath propagation scenario and reduce it to a two-path propagation one. To tackle this problem, a pre-localization algorithm is proposed. In our proposed algorithm, we use the reflection properties of UWB signals to extract information from the reflected signals in the multipath environment and ultimately reduce the multipath propagation scenario into a two-path one based on these extracted information. Our process of extraction involves the sampling of the received signals at three receivers during regular intervals, correlating the sampled signals with a predefined database of template reflected signals; and finally using a decision engine to determine the signals that would be used for generating the ellipse for target localization. Consequently, we were able to differentiate multipath signals from one another using the relationship between individual multipath signals and their respective angle of incidences; and ultimately select a set of reflected signals that would be suitable for the localization process described by existing elliptical based localization schemes.

Several IEEE standards for modern Wireless Sensor Network (WSN) radios make use of impulse radio ultra-wideband (IR-UWB). To keep power consumption to a minimum, pulses are grouped together in bursts. This paper presents a model used to analyze the relationship between DC power consumption, burst length and link budget for both peak and average power limited systems. Such a model is a crucial ingredient in the design of new wireless systems, when designing for maximum achievable distance with low power consumption. The main conclusions in this paper are that longer bursts turn out not to be more power efficient and an average power limited system gives a higher link budget.

We have developed and tested fiber optic electric and magnetic field sensors for ultra wideband (UWB) applications. The sensors are based on nonlinear effects in electro-optic (EO) and magneto-optic (MO) crystals. Unlike conventional antenna-based probes, EO and MO sensors are composed of all-dielectric materials and do not perturb the very fields that they measure. The sensors are small in size (less than 5mm in diameter), allowing them to be used in confined spaces and can be used with over 50 meters of optical fibers. These features make the sensor very well-suited for UWB applications and attractive for potential commercial use.

Ultra-wideband (UWB) technology is now becoming mature enough to play a crucial role in a large variety of pervasive wireless sensor network applications. One of these applications is represented by land seismic exploration for oil and gas reservior. Seismic exploration requires a large number (2000 nodes/sqkm) of sensors to be deployed in outdoor over large areas (typ. 30 sqkm) to measure backscattered wave fields. A storage/processing unit (sink node) collects the measurements from all the sensors to obtain an image of the sub-surface in real-time. The UWB technology is proposed in this paper for replacing the cable connections between the sensors and the sink. UWB is the most suitable wireless technology for this application as it guarantees high data rate over short range links and self-localization with sub-meter accuracy. An UWB sensor network based on Multi-Band OFDM is designed for the specific problem. Amendmends to ECMA 368 specifications are also identified to allow for energy aware beaconing and self-localization.
