基于消息队列的通信系统异步传送控制仿真

Simulation of Asynchronous Transmission Control in Communication System Based on Message Queue

传统方法对通信系统异步传送控制效果不佳,存在信号干扰及传送时间间隔较长等问题。为此引入消息队列技术,提出一种新的传送控制方法来解决以上问题。对通信系统的空时信道进行空时编码设计,实现空时信道的编码增益与分集增益;利用空时编码实现通信系统中继节点的空间分集,根据空间分集结果制订异步空时传送方案;采用消息队列技术构建通信系统异步传送控制模型,实现通信系统的异步传送控制。为了验证所提方法异步传送控制效果,设计对比实验。实验结果表明,上述方法的传送时间间隔较短,抗干扰能力强,平均分集增益高,说明所提方法更适用于通信系统的异步传送控制。

Traditional method has poor effect on the asynchronous transmission control of communication system, leading to signal interference and long-time interval. Therefore, this paper introduces the message queuing technology and proposes a new transmission control method. Firstly, we conducted the space-time coding design on the space-time channels of communication system, so as to achieve the coding gain and diversity gain of space-time channels. Secondly, we used the space-time coding to realize the spatial diversity for relay nodes in communication system. According to the spatial diversity result, we formulated the asynchronous space-time transmission scheme. After that, we used the message queue technology to construct the asynchronous transmission control model of communication system and thus to achieve the asynchronous transmission control for the communication system. In order to verify the effect of method, a comparative experiment was designed. Simulation results show that the proposed method has short transmission time interval, strong anti-interference ability and high average diversity gain, so it is more suitable for asynchronous transmission control of communication system.
