中文摘要：

声表面波标签因其自身固有生产工艺的缺点及容量有限而限制了其应用和发展。从实际生产的角度出发，以脉冲位置编码声表面波标签为基础，提出了中等容量和大容量声表面波标签的设计方案，在提高容量的同时可降低生产成本。该文核心内容为大容量声表面波标签的设计，其基于相关叉指换能器和排列组合原理，与之对应的两种阅读器结构方案也展开了讨论。

英文摘要：

The application and promotion of the SAW tag are unsatisfactory due to the inherent defects of the manufacturing technology and limitied capacity. From the perspective of practical production, the design scheme of medium capacity and largy capacity SAW tag based on the pulse position coding method is proposes, which can re- duce costs besides increasing capacity. The largy capacity SAW tag is designed based on the correlation inter-ditigal transducer（IDT） and permutations and combinations theory. At the same time, some ideas about the reader struc- ture for this large capacity SAW tag are given.
