It can effectively suppress the narrowband interference and wideband interference in GPS interferences simultaneously with the adaptive time-domain notch filtering canceling the narrowband interference and the power inversion algorithm suppressing the spatial interferences. The simulation shows that, in the presence of several strong interferences, such scheme can get an ideal outcome with the average suppression depth more than 50dB and can improve the performance of anti-jamming GPS receiver greatly.","PeriodicalId":211786,"journal":{"name":"2010 International Symposium on Signals, Systems and Electronics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129735164","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 grounded SRR results in a compacter size. The proposed metamaterial exhibits a negative effective permittivity ∊e and positive effective permeability μe under electric excitation, and its electric resonant frequency is easily changeable from 4.5GHz to 5.7GHz by adjusting the length of the folded arms. It is used to suppress the mutual coupling between elements in microstrip array by blocking the propagation of the excited surface waves in microstrip substrate, and eliminate the scan blindness in the infinite microstrip phased array. The results indicate its excellent application potential to improve the scanning performance of microstrip array. More interestingly, compared with the reported techniques, such as electromagnetic band-gap (EBG) structures and defected ground structures (DGSs), the new metamaterial almost has nearly zero thickness as an isolation wall, which means that it is very suitable for constructing the high-density array.","PeriodicalId":211786,"journal":{"name":"2010 International Symposium on Signals, Systems and Electronics","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114427111","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}

An adaptive IF-digital I/Q demodulator is designed, and all of its components are considered in turn.
