In this article we propose a low complexity algorithm for detection and localization of multiple targets using UWB sensor networks. We assume that the targets being tracked do not have any devices or tags attached. They are localized using scattered electromagnetic waves. Our envisaged sensor network consists of sensor nodes that can autonomously detect and localize the closest target. Those partial location estimates are mapped into images of an inspected area that are smoothed in time. This data fusion method does not require any data association or multi-hypothesis tests that are usually prerequisite in localization of multiple targets. This yields a significantly lower computational complexity compared to other algorithms. We demonstrate the performance of our algorithm by an experimental measurement using 6 sensor nodes.

Pulsed ultrawideband (UWB) signaling is widely used in indoor localization networks, in which data communications often occur concurrently. The receivers in such a network often have different complexity, performance, and energy consumption requirements. The goal of this paper is to design a coded-reference (CR) UWB scheme that enables simultaneous data transmission and high-precision localization while receivers with different performance and complexity requirements can flexibly choose their own operation modes. We start with the Barker codes and construct a set of orthogonal codes for CR signaling; compared with existing schemes, these codes have the desired autocorrelation properties required for high-precision timing extraction when the received signal is weak (transmission over a long distance). We also modify an existing hybrid coherent-transmitted-reference modulation format and apply the orthogonal codes designed so that both coherent and CR receivers can demodulate the same transmitted data while the fine-timing information required for high-precision localization is carried inherently in the transmitted signal. Timing synchronization and error performances of the proposed system are analyzed and simulated.

Ultra-wideband (UWB) multipath channels are assumed to have a sparse structure as the received consecutive pulses arrive with a considerable time delay and can be resolved individually at the receiver. Due to this sparse structure, there has been a significant amount of interest in applying the compressive sensing (CS) theory to UWB channel estimation. There are various implementations of the CS theory for the UWB channel estimation based on the assumption that the UWB channels are sparse. However, the sparsity of a UWB channel mainly depends on the channel environment. Motivated by this, in this study we investigate the effect of UWB channel environments on the CS based UWB channel estimation. Particularly, we consider the standardized IEEE 802.15.4a UWB channel models and study the channel estimation performance from a practical implementation point of view. The study shows that while UWB channel models for residential environments (e.g., CM1 and CM2) exhibit a sparse structure yielding a reasonable channel estimation performance, channel models for industrial environments (e.g., CM8) may not be treated as having a sparse structure due to multipaths arriving densely. The results of this study are important as it determines the suitability of different channel models to be used with the CS theory.

Gabor-division (GD) code division multiple access (CDMA) communication, which can provide almost flat power spectrum, has been recently proposed. Using a UWB Gaussian pulse generator implemented by CMOS technology as a fundamental component generating a chip waveform, we apply the GD-CDMA system for UWB communications. Time-frequency two dimensional spread spectrum (SS) codes with Markovity are employed. How Markovian SS codes flatten the spectrum of the transmitted signal is explained.

In this paper compressed sensing (CS) techniques are employed to develop reduced sampling rate strategies for channel estimation and data detection in impulse radio ultrawideband (IR-UWB) systems. In particular, first channel estimation algorithms based on Matching Pursuit (MP) and Basis Pursuit Denoising (BPDN) techniques are proposed. Then, it is shown how the channel estimates generated by these algorithms can be used in correlation-based CS detectors. Finally, the performance loss originating from CS is assessed analytically in a transmitted reference (TR) system.

Opportunistic Spectrum Access (OSA) is a promising solution to increase spectral efficiency in the Cognitive Radio (CR) framework. In OSA networks, unlicensed Secondary Users (SUs) need a Common Control Channel (CCC) to identify the spectrum opportunities, i.e., common spectrum holes unused by licensed Primary Users (PUs). To fulfill this requirement, the sharing of the spectrum sensing data via Ultra-wideband (UWB) has been proposed in the literature. In this paper we evaluate the design of a highly available underlay UWB signalling network for the exchange of sensing information among SUs avoiding harmful interference to PUs. We analyse the trade-off between the connectivity degree of a multi-hop underlay signalling network, related to the CCC parameters, and its coexistence with PUs. Moreover, we assess the performance of cooperative sensing in terms of detection probability accounting for the availability and the characteristics of the CCC. Results show that a correct dimensioning of the UWB signalling network allows to achieve high accuracy of PU detection avoiding harmful interference.
机会频谱接入(OSA)是认知无线电(CR)框架下提高频谱效率的一种很有前途的解决方案。在OSA网络中，未授权的Secondary user (SUs)需要一个Common Control Channel (CCC)来识别频谱机会，即未授权的Primary user (pu)未使用的公共频谱漏洞。为了满足这一需求，文献中提出了通过超宽带(UWB)共享频谱感知数据。在本文中，我们评估了一个高可用的底层UWB信令网络的设计，用于在单个单元之间交换传感信息，避免对单个单元的有害干扰。我们分析了与CCC参数相关的多跳底层信令网络的连通性及其与pu共存之间的权衡。此外，我们还根据可用性和CCC的特性，从检测概率的角度评估了协同感知的性能。结果表明，正确的超宽带信号网络尺寸可以实现高精度的PU检测，避免有害干扰。

This paper focuses on the design of Radio-over-fibre (ROF) links for ultrawideband (UWB) applications. Due to strict regulations, network architecture and technical feasibility, UWB ROF links must have 0 dB gain, low noise figure and low DC power dissipation. Due to the low power of UWB signals, pre-amplification is possible. Design rules for UWB ROF links with a pre-amplifier are presented. If followed, these rules enable design of links with a lower noise figure and power dissipation than previous design rules yield for general purpose ROF links. This is illustrated by a ROF link for UWB channel sounding that requires only 27.3% of DC power compared to a commercial link with similar gain and noise figure.

This paper addresses a cooperative communication scheme in a simple multi-node network of two mutually independent sources communicating over a common shared relay. We assume an Impulse Radio Ultra-Wideband (UWB) communication technique employed by all network nodes which influences used model of a channel impulse response. The signal received at the relay is processed by a Hierarchical Decode & Forward (HDF) strategy. Due to properties of a Hierarchical eXclusive Code (HXC) it is sufficient for the relay to fully decode only hierarchical symbols. The capacity region of the HDF strategy has a rectangular shape and exceeds the capacity region of a Joint Decode & Forward (JDF) concept. We assume a projection to given subspace at the input of the relay receiver to reduce the dimensionality of the signal. Impact of the choice of the subspace is analyzed in this paper. Various subspaces with different level of the knowledge of a Channel State Estimation (CSE) are considered. For different particular channel realizations, according to the chosen channel model, we numerically evaluate the MAC channel capacity. For comparison we also evaluate the classical MAC region as well as the true information theoretic channel capacity.

The Detect and Avoid (DAA) mechanism is a widely used technique in cognitive radios to support the coexistence of primary and secondary users operating in the same spectrum portion. In this paper we describe our experience in detecting WiMAX signal (operating as a primary user) in the 3.5 GHz range using the Ultra Wide-Band (UWB) test dongles from Wisair (operating as a possible secondary user of the spectrum). For this purpose a generic radiated test bed was prepared and two scenarios were considered in order to experimentally study the detection capability of DAA block within the WISAIR UWB devices. The detection results are presented in terms of the received signal strength and the sensitivity of the device.

In this work we present a low-complexity, ultra-wideband (UWB) pulse generator which complies with the Sub-GHz band in FCC regulation. This pulse generator uses a simple common emitter amplifier followed by RC high-pass filter as a differentiator to generate the monocycle pulse directly. The circuit provides a monocycle pulse when activated by a ramp edge of an external trigger signal provided by a dedicated circuit exploiting also the pulse width duration tuneability by varying the edge slope. An ultra-short monocycle pulse of 1ns pulse duration up to tens of nanosends has been demonstrated with reduced ringing levels, and good symmetry. The design is versatile and may be used in a variety of integrated circuits UWB modulation schemes and systems. A discrete element board with commercial components has been implemented as prototype and good agreement between the measured and calculated results was achieved with a 50 mW power consumption from a 3.3V power supply.
