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 multi-stage wireless relay system is introduced. The system consists of a central station and multiple user stations. The subscriber stations are randomly distributed around the central station. The multi-level relay of the user station allows the central station to communicate with each user station. System hardware is simple, occupy less frequency resources, low cost. The system can be used as equipment monitoring or information transfer. A media access method is proposed and its performance is analyzed. The simulation results show the effectiveness of this method.
