Wireless Channel Sounding using Distributed and Synthetic Arrays

随着无线系统采用越来越复杂的方法和技术来实现更大的容量、可靠性和能量效率，它们的性能对更宽范围的传播损伤变得越来越敏感，并且信道模型变得越来越复杂。我们建议开发新的和改进的方法，用于表征无线信道使用合成或分布式阵列，从而支持下一代无线系统的设计和部署在新的和具有挑战性的情况。预期成果包括：1）更经济的信道探测器体系结构，2）用于从原始信号数据提取信道特性的更好方法，3）用于以信道模型的形式捕获信道特性的更好方法。

As wireless systems have adopted increasing complex methods and techniques to achieve greater capacity, reliability and energy efficiency, their performance has become increasingly sensitive to a broader range of propagation impairments and channel models have become evermore complex. We propose to develop novel and improved methods for characterizing wireless channels using either synthetic or distributed arrays and thereby support the design and deployment of next generation wireless systems in new and challenging scenarios. Anticipated outcomes include: 1) more cost effective channel sounder architectures, 2) better methods for extracting channel characteristics from raw signal data, 3) better methods for capturing the channel characteristics in the form of channel models.
