本文介绍了一款宽带MIMO(多路输入多路输出)信道探测仪,它是基于多端口网络分析仪和快速开关而构建的,二者分别由笔记本电脑中的应用软件进行控制。该信道探测仪具有多种功能,可以配置频率带宽、发射天线和接收天线的数量等系统参数。唯一不便的是,在测量过程中信道必须保持稳定。
This article describes a wideband MIMO (Multiple Input Multiple Output) channel detector built on a multi-port network analyzer and fast switch, both controlled by application software in a notebook computer. The channel detector has multiple functions to configure system parameters such as frequency bandwidth, number of transmit antennas and receive antennas. The only inconvenience is that the channel must be stable during the measurement.
