摘要
协作分集技术使得具有单根天线的通信终端可以共享彼此的天线而产生一个虚拟多输入多输出(MIMO)系统,解决了通信终端受尺寸和硬件复杂度的限制难以实现多天线的问题,因而逐渐引起人们的关注。文中讨论了采用协作的无线传感器网络(WSN)在井下通信和人员定位的应用,并指出了其在煤矿安全监测和矿区通信中要解决的问题。
Cooperation diversity enables single antenna communication terminal to share each other＇ s antenna and forms a virtual multiple input multiple output （MIMO） system, thus solving the problem that it is hard to implement multiple antennas in the communication terminal due to the size or hardware complexity limits. Therefore, cooperation diversity gradually attracts attention form the people. This paper discusses and forecasts the application of cooperation based wireless sensor network in mine safety and personnel positioning, and points out its problems to be solved in safety monitor and communications of the mining areas.
