Improving the usage of communication spectrum resources is critical to future wireless systems. The OSTARA project focuses on the development of RF photonic techniques that support the ability to simultaneously transmit and receive in wireless devices. The effort involves a mix of theoretical development (specifically investigating potential improvements in capacity), as well as systems validation efforts involving building an opto-cancellation circuit capable of cancelling out co-site interference associated with simultaneous transmission and reception. . Specifically, the theoretical component of the effort will involve using ray-tracing to understand the role of cancelation of multipath components on communication rate, as well as an investigation into the impact of idealized cancellation on network capacity using graph coloring. The systems component of the effort will involve developing photonic circuits that subtract off the transmitted signal from the receiver chain, as well as potential multipath images of the transmitted signal. Validation will involve field testing the opto-canceller by setting up test scenarios on the ORBIT testbed at WINLAB.Broader Impact: The proposed research will improve the spectrum utilization of future wireless systems, an issue of critical national importance. Additionally, the project will educate students and post-doctoral fellows in the inter-disciplinary area of RF-photonics as applied to advanced radio systems.

提高通信频谱资源的利用率对于未来的无线系统至关重要。 OSTARA 项目专注于射频光子技术的开发，支持无线设备同时传输和接收的能力。这项工作涉及理论开发（特别是研究容量的潜在改进）以及系统验证工作，包括构建能够消除与同时传输和接收相关的共站干扰的光消除电路。 。具体来说，该工作的理论部分将涉及使用光线追踪来了解多路径分量取消对通信速率的作用，以及使用图形着色来调查理想化取消对网络容量的影响。这项工作的系统部分将涉及开发光子电路，从接收器链中减去传输信号，以及传输信号的潜在多径图像。验证将涉及通过在 WINLAB 的 ORBIT 测试台上设置测试场景来对光消除器进行现场测试。更广泛的影响：拟议的研究将提高未来无线系统的频谱利用率，这是一个至关重要的国家问题。 此外，该项目还将对应用于先进无线电系统的射频光子学跨学科领域的学生和博士后进行教育。
