摘要
多输入多输出(Multiple Input Multiple Output,MIMO)无线传输技术可以在不增加带宽和天线发射功率的情况下,成倍地提高无线通信系统的信道容量。文中基于嵌入式实时操作系统,实现了MIMO传输系统中的协议处理、业务汇聚和高速数据传输。采用VxWorks操作系统为平台,以TCP/IP协议为基础,提出了实现MIMO系统中高层协议的总体方案。实验表明,采用的高层协议可以很好地支持话音、图像和数据传输,也可以为未来移动通信高速数据传输、无线资源管理、无线网络协议及规划提供良好的支持。
The Multiple Input Multiple Output (MIMO) technologies can multiply the channel capacity and reliability of wireless communication system within the same frequency band at no additional power expenditure. Based on embedded operation system, the high layer protocol model and its implementation in MIMO wireless communication system is introduced. The structure proposed not only can support future voice, image and data transmission, but also can provide better support for future mobile communication, radio resource management and network protocol layout.
