As an application example, the commonly used data mining techniques such as Multilayer Perceptron (MLP), M5 model tree, and Reptree are employed to model the characteristic impedances of elliptic and circular-shaped microshield lines as a function of the geometry and substrate parameters. The training and validation data are provided from the analytical formulae. Thus the black- box models are achieved for these types of wave guiding systems where their characteristic empedances are evaluated through data mining techniques to be used in the analysis and design of the microwave circuits.

They appear not to take full advantage of some special features offered by the impulse radio UWB transceivers, such as ultra-wide bandwidth and very short duration pulses. To move beyond this shortcoming, in this paper, we have reviewed our recent innovations in using nonlinear signal processing technologies, in particular, the Teager-Kaiser operator and the square law device, in energy detection based UWB transceivers. It is found that nonlinear signal processing technologies can mitigate not only the destructive effects caused a narrowband interference but also those caused wideband noises, and hence can significantly improve the bit-error-rate performance of energy detection based UWB transceivers no matter when a narrowband interference is present or not. In summary, use of nonlinear signal processing technologies is a groundbreaking innovation and presents a potentially new horizon for research and development of UWB systems.","PeriodicalId":260071,"journal":{"name":"2012 IEEE International Conference on Ultra-Wideband","volume":"26 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":"123431521","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}

This paper discusses the RAKE reception technique by using the multicarrier template waveform in the UWB-IR (Impulse Radio) system to compensate the influence of multipath. The template waveform in the UWB receiver is modified to the multicarrier pulse, because the power spectrum density can be controlled to weight for the sub-band pulses. The BER (Bit Error Rate) performance is improved, because more powerful path can be detected in each sub-band pulse of the multicarrier template waveform and the correlation values of the RAKE branches can be combined efficiently.","PeriodicalId":260071,"journal":{"name":"2012 IEEE International Conference on Ultra-Wideband","volume":"48 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":"130420472","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}

Thereafter, the MLP NN is validated utilizing the CST MWS test data. Comparison of the reconstructed data with the target data shows that MLP can be used as a very efficient technique to predict the reflection phases of reflectarray. The MLP NN modeling is applied to the minkowski and circular ring shaped radiators and their reflection characteristics are obtained within the continuous domain of the geometrical parameters, substrate and frequency. Some typical reflection phase characteristics are given. Furthermore, a minkowski reflectarray of 5 × 5 on Taconic RF-35 with εr =3.5 and tan δ =0.0018 is designed and its radiation patterns are simulated by using CST MWS. The bandwidth characteristics of the array are also observed within the X-band frequency range.","PeriodicalId":260071,"journal":{"name":"2012 IEEE International Conference on Ultra-Wideband","volume":"48 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":"126531455","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}

In the considered scenarios the presence or the absence of an object is observed by the sensors independently. Due to noisy communication channels, the interfered observations are fused into a reliable global decision in order to increase the overall detection probability. An approach based on information theory, that aims at maximization of channel capacity, is employed. It allows for analytically described allocation of total given power to the sensors and, thereby, optimizes the overall detection probability. Furthermore, we demonstrate the feasibility of object detection by using the introduced power allocation method in ultra-wide bandwidth signaling systems.","PeriodicalId":260071,"journal":{"name":"2012 IEEE International Conference on Ultra-Wideband","volume":"26 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":"127691916","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}
