我们提出了一个描述的当代性能评估方法的频谱共享技术（包括动态频谱接入（DSA）/认知无线电（CR）），和利益相关者的观点方面的缺点和由此产生的延迟现场过渡的影响。的缺点进行检查，以产生一组理想的新属性，更有能力的测试和评估（T&E）系统和方法。描述了旨在解决这些DSA/CR T&E缺点的使用动态频谱环境仿真器（DYSE）的正在进行的研究和开发（R&D），包括雷达-长期演进（LTE）网络共享示例、使用802.22的TV空白空间共享示例以及具有用于通信和PNT的共享RF源的位置/导航/定时（PNT）示例。
We present a description of contemporary performance evaluation approaches for spectrum sharing technologies (including dynamic spectrum access (DSA)/cognitive radios (CR)), and the perspectives of stakeholders with respect to shortcomings and resultant delayed field transition impacts. The shortcomings are examined to generate a set of desirable new attributes for more capable test and evaluation (T&E) systems and methods. Ongoing research and development (R&D) using the DYnamic Spectrum Environment emulator (DYSE) aimed at addressing these DSA/CR T&E shortcomings is described including a radar-Long Term Evolution (LTE) network sharing example, a TV whitespace sharing example using 802.22, and a position/navigation/timing (PNT) example with shared RF sources for communications and PNT.
