The developed strategy for a Single-Input Multiple-Output Orthogonal Frequency Division Multiplexing (SIMO-OFDM) communication system consists to prevent the interceptors to achieve a good blind channel estimation while allowing an accurate channel identification by the drone in the same wireless transmission conditions. To do so, a relevant selection of the communication parameters such as an appropriate data model with a specific data power is proposed. The channel estimation error variance of the pilot-based and blind-based techniques are compared using the Cramèr Rao Bound (CRB). Simulations show that, under the same wireless transmission conditions, the blind channel estimation approach achieves the worst performance ensuring therefore the protection of the transmitted data.","PeriodicalId":371206,"journal":{"name":"2017 Seminar on Detection Systems Architectures and Technologies (DAT)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125432494","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}

To this end, we propose a new Constant False Alarm Rate (CFAR) detection approach based on evaluating the abrupt changes in the background power level samples i.e number of interfering target and/or clutter edge. The proposed new detector is a CFAR detector based on a difference hypothesis of second order statistics, referred as SOD-CFAR detector. Unlike some recent works that use the information theoretic criteria (ITC) or the variability of the background clutter power level samples, this contribution detects the abrupt changes, analyzes the distribution exponentially of the remaining samples and select the homogeneous window based on the second-order statistics and the Shapiro-Wilk exponentially test. The proposed CFAR detector does not require any prior information about the background environment. Therefore, the performances of the proposed detector combine the advantages of the Order Statistics-CFAR (OS-CFAR) and the Cell Averaging CFAR (CA-CFAR) detectors to immune to the presence of randomness interfering targets among the reference cells. Numerical simulations that validate the performances of the proposed detector, in both homogeneous and nonhomogeneous environments, are presented.","PeriodicalId":371206,"journal":{"name":"2017 Seminar on Detection Systems Architectures and Technologies (DAT)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126411227","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}
