It exploits the idea of nonparametric detection, which is always utilized in radar systems for detecting targets in a background of noise with unknown statistical properties. The proposed nonparametric TOA estimator is obtained by basing a well-known generalized sign detector upon conditional statistical test with only a symmetry distribution assumption on the noise probability density functions. The main advantage of nonparametric estimators for ultra wide band signals is that they can be implemented by high sampling rate low resolution ADCs or fast comparator, instead of high sampling rate high resolution ADCs which are too complicated and power-hungry to implement. The effectiveness of our nonparametric detection-based estimator is demonstrated by comparing with energy-detection (ED) estimators via simulation.","PeriodicalId":260071,"journal":{"name":"2012 IEEE International Conference on Ultra-Wideband","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130423815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The filter is composed of microstrip lines with shorted stubs acting as a high pass filter (HPF) on top side and dumbbell shaped defected ground structures (DGSs) on bottom side acting as a low pass filter (LPF). The seventh order high pass filter structures and three dumbbell shaped DGS resonators combined on a single layer microstrip substrate are optimized using microwave circuit and electromagnetic (EM) simulation tools to obtain the ultra-wideband bandpass filter. The designed compact filter has 0.9 dB max insertion loss in-band, no harmonics are observed up to and above 12 GHz and finally, it has a good selectivity. The designed hybrid circuit is a production friendly and low cost bandpass filter which has a controllable pass- and rejection band nature.","PeriodicalId":260071,"journal":{"name":"2012 IEEE International Conference on Ultra-Wideband","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123409062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A recently proposed multichannel autocorrelation receiver (AcR) can break this rate limit due to its multicarrier signal demodulation capability. In this paper, the hardware implementation of this receiver architecture is addressed. We focus on the multiplication device, which is a core part of the AcR and introduces strong interference due to nonlinear effects. To analyze the signal-to-interference ratio performance of the receiver system, a combined Wiener-Hammerstein system model of the multiplication device is introduced. It is shown that the receiver performance strongly depends on the input power of the nonideal multiplier devices.","PeriodicalId":260071,"journal":{"name":"2012 IEEE International Conference on Ultra-Wideband","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115329511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By extending the feed and slitting a slot in the radiator, another UWB antenna with a notched band of 3.3-3.6 GHz is achieved. The via and the extended feed can be viewed as a shunt LC-resonator and the resonant frequency can be controlled by adjusting the size of the slot.

Our goal is to help software and hardware designers in improving the state-of-the-art in UWB-based robotic localization. We developed a test-bed where an UWB transmitter is attached to a mobile robot. By combining the received signals with the robot's position log acquired through the dead-reckoning sensors, we obtain UWB signals which are well referenced with respect to the transmitter-receiver distance and orientation. In addition, we provide a model for every component of the setup. The entire setup allows us to simulate from first principles every aspect of an UWB localization system and then to implement low-level signal processing as well as higher-level modulation and localization techniques. We implement an Automatic Gain Control (AGC) algorithm to demonstrate the rapid proto-typing capabilities of the test-bed. Our work shows how an UWB robotic system and its models can be involved in all phases of the development of a technology that can help robot's navigation, localization and communication algorithms.","PeriodicalId":260071,"journal":{"name":"2012 IEEE International Conference on Ultra-Wideband","volume":"270 1-2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123716051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their UWB impulse responses are captured using an m-sequence method which provides high signal quality by means of ultra low jitter and noise. The size of the objects is in the range of the coherence length and smaller than the footprints of the antennas. The impulse responses depend on the moisture content (dielectric properties) and the geometry. Multivariate calibration is applied in order separate these influences and to develop a statistical model for the moisture content.

The proposed cascode LNA is designed and simulated in the IBM 0.13 μm CMOS technology. A low and flat NF (<;2.0 dB) is achieved in a wide frequency range (400 MHz-3.3 GHz). A gain of greater than 10 dB with a 16.5 dB peak is obtained. The input matching is better than -10 dB. The total power consumption is only 13 mW.
