摘要
Abstract
Combining time slot mechanism with Manchester encoding, a new algorithm is proposed based on binary search algorithm and ALOHA algorithm. Tags, whose identifiers (TID) accordance with the principle of "x-dimensional code distance equals to x", can be accessed in one slot. At least three TIDs can be recognized at the same time based on regulation of code distance inversion. Time slot reservation method is recommended to restrain empty slot's generation, then access speed and efficiency can be improved. Simulation results show that the new algorithm and time slot reservation method can not only increase the access rates, but also improve tag' s accessing efficiency.关键词
