Additionally the technique provides a considerable degree of robustness and alleviates the problem of missed tags. A theoretical discussion of the underlying principle is done. We provide simulation results when this technique is used specifically for the EPC Gen 2 protocol; the resultant increase in identification rate is 20% when two tag signals are simultaneously decoded and 30% when three tag signals are simultaneously decoded. Experimental results presented show that the extracted individual tag signals (when there is a collision of two or more tag responses) are virtually identical to the single tag signal. We believe that the signal extraction technique discussed here will eventually be a standard feature of all base stations.","PeriodicalId":206458,"journal":{"name":"Fourth IEEE Workshop on Automatic Identification Advanced Technologies (AutoID'05)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115156977","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}
