介绍了一种开放接入的宽带多天线无线试验床。试验台采用基于软件无线电技术的四发四收四天线系统。它在2.4 GHz ISM频段运行，支持与IEEE 802.11a/g标准兼容的射频带宽。开发了机器人定位系统，自动控制天线阵的位置和方向，使自动化测试成为可能，并极大地缩短了工程时间。试验台被配置为可以由互联网上的任何计算机控制。这使得远程调试和测试成为可能。这一测试自动化和通过互联网远程访问的特点被设计到试验台中，使其成为其他研究人员的宝贵资源。已经开发了一套软件来支持使用试验床的研究，目前的重点是MIMO信道特性和MIMO-ofdm分组通信。已经为试验台开发了数据采集系统和离线处理系统，并已用于空中测试，以便为正在进行的IEEE 802.11n标准化活动产生结果。
This paper introduces an open access wideband multiantenna wireless testbed. The testbed is configured as a four transmit antenna by four receive antenna system based on software defined radio technology. It operates in the 2.4 GHz ISM band and supports an RF bandwidth compatible to IEEE 802.11a/g standard. A robotic positioning system has been developed to automatically control the position and orientation of the antenna array, which makes automated testing possible and greatly reduces engineering time. The testbed is configured such that it can be controlled by any computer on the Internet. This makes remote debugging and testing possible. This characteristic of test automation and remote access through Internet was designed into the testbed to make it a valuable resource to the other researchers. A set of software has been developed to support research using the testbed, with the current focus on MIMO channel characterization and MIMO-OFDM packet communications. A data acquisition system and an offline processing system have been developed for the testbed and have been used for over the air testing to produce results for the ongoing IEEE 802.11n standardization activity.
