摘要
本文讨论了语音寻呼的实现方法和关键技术，分析了语音寻呼系统的几个主要参数及走向实用化的途径，给出了文本和语音综合的寻呼系统的容量方程，在理论分析的基础上提出了一个码率为２４００ｂｉｔ／ｓ的与ＰＯＣＳＡＧ码兼容的实验综合寻呼系统。
In this paper, some key techniques and realizing methods in voice paging system are discussed, the main parameters are analyzed and the ways to practise are pointed out, and the system capacity equation for text voice integrated paging system is presented. Based on the theoretical analysis, a 2400 bps text voice integrated experiment system, which is compatible with POCSAG code, is developed. The theory and methods presented here will also apply to systems with higher code rate, such as FLEX,ERMES, etc.
