基于软件编码的FLEX高速寻呼测试仪的研制 The Research of High-Speed FLEX Pager Tester on Software Coding 袁兰英 YUAN Lan\|ying WU Hai\|bo LUO Kun 1 first-author 吴海波 1 罗琨 1 武汉大学电子信息学学院,武汉,430072 武汉大学电子信息学学院,武汉,430072 College of Electronic Information, Wuhan University College of Electronic Information, Wuhan University 基于 FL EX和 POCSAG寻呼协议 ,采用单片机 AT89C5 5为控制核心 ,以 MCS- 5 1汇编语言实现软件编码 ,研制了一套兼容 POCSAG协议的 FL EX高速寻呼测试仪 .本文详细讨论了实现 FL EX高速寻呼协议的软件编码技术 .在对数据块进行交织时 ,提出了一种简化的软件编码措施 ,将多相复用模式的交织数据块简化为单相模式进行处理 ,从而减小了编码难度 Basing on paging protocol of POCSAG and FLEX, develops a POCSAG & FLEX pager tester, the kernel of which is AT89C55 on MCS 51 instruction set. This paper takes simplified Software coding measures that simplify interlaced multi phase data block as solo phase to lessen coding difficulty. It proves that the tester has steady performance. FLEX high speed paging protocol is introduced firstly in the paper, and then software coding technology of FLEX is illuminated in details.
