摘要
在由多基站组成的无线同播寻呼网中，相关发信机的信号发射到重叠区时存在时延差，而当时延差较大时就容易在重叠区产生误码、丢码现象。针对无线同播寻呼时延均衡的要求，设计了以ＡＴ８９Ｃ５１单片机为核心的寻呼发信时延器。文中介绍了发信时延器的硬件与软件设计。该时延器在寻呼网上的实际运行表明：各项性能指标达到了预定要求。
n the wireless synchronized paging networks consisting of multibase stations,there
exists time delay when the launching signal is transmitted to the overlapping zones.In case the
delay is so long,it will cause error code or lose code.In view of the requirement of balanced time
delay for the wireless synchronized paging, a balanced timedelay device based on AT89C51 is
designed.This paper describes the hardware and software design of the device,and the practical
operation proves that all performance of the device havemet the preset requirement.
