摘要
结合动态帧时隙算法的理论分析与多标签估算的数学建模,并在EPC协议的基础上对选择Q值估算方法和泊松估算方法进行仿真分析,总结两种方法性能的优劣,提出了一种新型多标签估算方法,旨在解决剩余多标签估算准确性低的问题。仿真结果表明,新型估算方法在估算标签数目上的性能更优,减少了总时隙数目,从而提高了系统的时隙利用率。
This thesis combined with the the theoretical analysis of dynamic framed slotted algorithm and mathematical mode-ling of multi-tag estimation.It simulated and analyzed the property of the slot-count（Q） selection algorithm which was on the basis of the EPC protocol,and the poisson estimation methods.It proposed a new method of multi-tag number estimation to resolve the problem of low accuracy of multi-tag estimation.Simulation results show that the new method has a better performance on tags number estimation,reduces the total number of time slots,and improves the system utilization rate.
