摘要: Radio frequency identification (RFID) is rapidly come into our lives in recent years, and it widely used the areas of logistics, production, transportation so on. The technology anti-collision a key RFID. Most algorithms proposed before are based on TDMA. When number tags very large, can not well solve problem. In this paper, an algorithm CDMA proposed, using m sequence as spreading code combined with S-ALOHA that known CMS-ALOHA algorithm. This paper analyzes throughput CMS-ALOHA, gives mathematical analysis. Experimental results show has good performance.
