我们描述了一种测量双向移动无线电信道的新技术。该信道被称为双向，因为它包括在链路两端，即基站和移动站的定向扩展。我们使用了双阵列多路复用技术，该技术由接收端的开关线阵和发射端的虚拟阵列组成。测量的微蜂窝场景是一个开放和封闭的庭院，具有不同的发射机位置。利用交替估计和波束形成技术来评估数据，该技术依赖于位置参数的(么正)ESPRIT估计和随后的波束形成以进行复权重提取。在发射机站点使用两轴交叉阵列避免了前向-后向歧义。给出的示例性结果表明，提取的方向信息与物理环境具有很好的一致性，并给出了其散射特性的指示。
We describe a novel technique to measure the double-directional mobile radio channel. The channel is called double-directional since it includes directional spreading at both link ends, namely the base station and the mobile station. We use a double-array multiplexing technique consisting of a switched linear array at the receiver and a virtual array at the transmitter site. The measured microcellular scenarios are an open and a closed courtyard with different transmitter positions. The data are evaluated with an alternating estimation and beamforming technique that relies on (Unitary) ESPRIT estimation of positional parameters and subsequent beamforming for complex weight extraction. Usage of a two-axis crossed array at the transmitter site avoids forward-backward ambiguity. The presented exemplary results show a good agreement of the extracted directional information with the physical environment and give an indication of its scattering properties.
