In the cooperative sensing, observations of multiple secondary users (SUs) are used to detect presence of PS. There are two approaches in cooperative sensing. The first approach is non-weighted cooperative sensing (NWCS). The second approach is a weighted cooperative sensing (WCS) where the weight is used to enhance the sensing performance. In this paper, we study a WCS, where the weight is designed based on a PS signal energy and the noise power. To estimate the PS signal energy, an estimation method is employed. In addition, our WCS implements plural antenna elements to suppress the effect of Rayleigh fading. Computer simulations show that the proposed WCS can outperform the conventional NWCS under shadow and Rayleigh fading environment.","PeriodicalId":334671,"journal":{"name":"2010 IEEE Radio and Wireless Symposium (RWS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129276251","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 system employs commercially available components including an Agilent 8363B phase network analyzer (PNA) and an Agilent 85070D dielectric probe. Instead of the Agilent software three material calibration technique, we propose a four material calibration method across the frequency range of 3–17 GHz for more robust measurements of the complex permittivity. Experimental results on human and snake tissues show the non-homogeneous nature of biological tissues and also illuminate the dependence of complex permittivity on tissue temperature. Building upon the differences and also the variation seen in complex permittivity in literature between normal and cancerous breast tissue across this frequency range, we propose a technique which utilizes a neural network where multiple measurements are input in making the final decision on whether or not the tissue under test is cancerous. Simulation results using Ansoft HFSS are provided here and show the potential of microwave diagnosis of breast cancer.","PeriodicalId":334671,"journal":{"name":"2010 IEEE Radio and Wireless Symposium (RWS)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124426983","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 topology provides significant advantages in easing input/output matching constraints inherent in asymmetric Doherty amplifiers where the asymmetry necessitates unequal device geometries for the peaking and carrier sub-amplifier circuits. Excellent high efficiency performance (45% @ 8 dB power back-off) is demonstrated by implementing the Doherty amplifier using an advanced prototype LDMOS device technology developed at Freescale Semiconductor. The amplifier achieves a saturated output power greater than 450W at 2.14 GHz when biased with a 28V supply. When driven with a single carrier W-CDMA signal, an efficiency of 45% is achieved at 8 dB power back-off. Moreover, when linearized with a digital feedback pre-distorter the amplifier achieves an ACPR better than −55 dB.","PeriodicalId":334671,"journal":{"name":"2010 IEEE Radio and Wireless Symposium (RWS)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120955647","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}
