摘要：

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