一种基于二进制码调制的射频识别防碰撞算法
A Radio Frequency Identification Anti-collision Algorithm Based on Binary Code Modulation
摘要
Abstract
To improve the identification efficiency and reduce the communication overhead,a novel algorithm,Binary Code Modulation Algorithm( BCMA) is proposed. BCMA works as follows:the activated tag generates and sends back a 2m bit binary code,Master Control Relay(MCR),on which the location information of the tag’s ID in the multi-branch tree is modulated. After receiving the MCR,the reader finds out the collided bits,demodulates the branch information,and groups the tags into determinate subsets. It is obvious that BCMA avoids generating idle slots. Analysis results and simulations show that compared with other existing multi-branch algorithms, as the common octree algorithm, BCMA improves the system throughput by 168% .关键词
