摘要

最近在马里兰州的巴尔的摩进行了实验测量,以确定在低层城市环境中军用UHF频段运行的多输入多输出(MIMO)无线电链路的信道特性。测试设备提供了一个非实时的2 × 3 MIMO系统,其中两个发射天线可以被从短(亚波长)到很长(按城市街区的顺序)的距离分开。信道容量,从测量的信道传输矩阵计算,然后可以表征为发射和接收天线之间的空间关系的函数。初步结果提出了选择的传统和分布式MIMO几何。

Cooperative MIMO field measurements for military UHF band in low-rise urban environment
Experimental measurements have recently been taken in Baltimore, Maryland, to determine the channel characteristics pertaining to multiple-input multiple-output (MIMO) radio links operating in military UHF band in a low-rise urban setting. The test equipment provides a non-realtime 2 times 3 MIMO system in which the two transmit antennas can be separated by distances varying from short (sub-wavelength) to very long (on the order of city blocks). Channel capacities, computed from the measured channel transfer matrices, can then be characterized as a function of the spatial relationships among the transmit and receive antennas. Initial results are presented for selected conventional and distributed MIMO geometries.
