摘要
介绍了使用Matlab模块仿真的方法开发分布式空时编码实验平台。该平台加入了信道状态信息,接收端由信道状态信息得到反馈信息,中继节点据此对原信号进行预处理,从而减小了信道相关性,提高了系统的可靠性。不仅可以完成对接收端由信道状态信息得到反馈信息的仿真,通过对该反馈信息的调用,还可以实现对原信号进行预处理,减小信道相关性,从而提高系统仿真的可靠性。在通信原理教学过程中,将该仿真实验和电路实验系统结合使用,有效地弥补了电路实验系统的不足。
An improved distributed space-time code is proposed which is based on MATLAB simulations.In this scheme,the channel state information is considered by the receiver to obtain the current feedback information,and the original signal data pre-processing in the relay nodes is made according to the channel state information,so that the channel-dependent interference is overcome and the reliability of the system is improved.The proposed experiment has been used in the process of teaching,and the result shows that it is an efficient way to make up shortages of traditional communication circuit experimental system.
