The hybrid algorithm is a combination of the energy detection and the cyclostationarity-based methods. In the majority of related works, the input signal for the energy detection is modeled with a lognormal distribution without considering the cyclostationarity of signal. However, primary signals may have other behaviors with different cyclostationarity levels. Those behaviors depend on the modulation scheme used and the traffic statistics of the primary user. Therefore, the hybrid method is evaluated considering several input signal models, which provide different levels of cyclostationarity. Additionally, a measured signal is used for evaluating the energy detection and the proposed method. The performance of the proposed method shows a detection gain in relation to the energy detection. The proposed method takes advantage of the higher accuracy of cyclostationarity method and the simplicity of energy detection. The obtained results are important in the investigation of a more generic and more accurate method for detecting primary users in systems such as wireless sensor networks.","PeriodicalId":142095,"journal":{"name":"2016 1st International Symposium on Instrumentation Systems, Circuits and Transducers (INSCIT)","volume":"194 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123658381","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}

C-RAN uses baseband processing units in a central server which connects to the radio front-ends at cell sites via the so-called fronthaul network. The fronthaul infrastructure is currently provided by CPRI (Common Public Radio Interface) and OBSAI (Open Basestation Architecture Initiative) industry standards which use dedicated optical links with high deployment costs. An alternative is to use Ethernet technology aiming to reuse of network infrastructure available in many commercial buildings. However, in contrast to the traditional synchronous fronthaul, Ethernet suffers with packet delay variation (PDV) and challenging synchronization recovery. This work presents a complete and flexible testbed to evaluate Ethernet-based fronthaul. The system is validated via extensive measurements that show the effects of synchronization procedures and network impairments on regenerated clock phase noise.","PeriodicalId":142095,"journal":{"name":"2016 1st International Symposium on Instrumentation Systems, Circuits and Transducers (INSCIT)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124095940","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 performance of wireless communications systems is mainly limited by fading produced by multipath propagation. In order to minimize the fading effects, channel coding and diversity techniques are often used in wireless systems. Among the known coding techniques in the literature, the wavelet coding presents an interesting alternative to overcome the multipath fading, since it gets performance gain by transmitting in time diversity without compromising spectral efficiency. This paper investigates the use of wavelet coding in a system that operates over a wireless channel to control the rotation frequency of the direct current motor. Aspects such as packet error probability performance, hardware complexity and processing delays due to wavelet coding are analyzed, as well as its beneficial effects on the control system. In the proposed system, the wavelet coding was embedded in PIC microcontroller and a radio transceiver XBee is used to establish a wireless link. The obtained results demonstrate a reduction of fading effects on the control signal, as well as, a low cost for hardware implementation and a small impact on system processing time.","PeriodicalId":142095,"journal":{"name":"2016 1st International Symposium on Instrumentation Systems, Circuits and Transducers (INSCIT)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126963227","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 control of milk composition and detection of adulteration in raw materials are crucial in order to assure the quality of dairy based products. Different technologies for the monitoring of milk constituents in substitution of chemical processes have been reported. Recent studies showed that microwave sensors have a good potential for measuring the milk moisture content. Here, we proposed a measurement system using a resonant cavity sensor for the determination of total solids and fat contents. Its main advantages comprises non-invasive and non-destructive characteristics and fast response. Additionally, the geometry of the cavity is adapted for easy deployment in industrial facilities. We used nine characterized milk samples in order to demonstrate the feasibility of the system. The results showed a good correlation between the system response and the volume fractions of total solids and fat constituents, proving that the system is a useful platform for the analysis of milk quality.","PeriodicalId":142095,"journal":{"name":"2016 1st International Symposium on Instrumentation Systems, Circuits and Transducers (INSCIT)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114226362","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}
