摘要: 本工作提出一种基于盲源分离的动态帧时隙估计算法(BSDFA),由于天线数量对采用了盲源分离思想的帧时隙估计算法有影响,进一步提出根据天线数量、标签数量和初始帧时隙数来精确估计下一帧的帧时隙数的方法,以此提高帧识别率。通过验证,基于盲源分离的动态帧时隙估计算法的帧识别率高于盲分离的帧时隙超高频RFID系统防碰撞算法(BSFA)的帧识别率。

Abstract: In this paper, a dynamic frame size estimation algorithm based on blind source separation (BSDFA) is proposed. Its core idea is to estimate the number of slots in the next frame according to the number of antennas, the number of tags and the number of slots in the previous frame.The experimental results show that our proposed algorithm has better performance than BSFA algorithm.
