多级无线接力系统

Multi-level Radio Relay Communication System

介绍了一种新颖的多级无线接力系统。该系统由一个中心站和多个用户站构成。用户站随机地分布在中心站周围。通过用户站的多级接力,中心站可以和每一个用户站进行通信。系统硬件简单,占用频率资源少,成本低。该系统可用作设备监控或信息传输。提出了一种媒介接入方法,并对其性能进行了分析,仿真结果表明了这种方法的有效性。

A novel kind of radio relay communication system is introduced in this pap er.The sys-tem is consisted of a center station a nd several users.Users distribute r andomly around the center station.With the help of some users' multi -level relay,the center station can communicate with each user in t he system.Simple hardware,needing only a little frequency reso urce,and it cost low.The system can b e ap-plied in equipment surveillance and control system,information transm ission system and so on.A kind of medium access protocol is proposed a nd analyzed in detail.Numerical results show the efficiency of the method.
