This Small Business Technology Transfer Research (STTR) Phase II project will extend the basic science of linear interference delay effect filters, enabling ultra-wideband tunable RF filters for all types of RF receivers and instrumentation. It will also extend the engineering science of implementing such filters as integrated circuits. And, its distortion filtering aspect will enable enable signal agnostic,adaptive cancellation of wideband, and in-band, interference, for anti-jamming applications as well as to enhance signal quality for the consumer.The broader impact/commercial potential is that it will help achieve the national goal of expanding access to RF spectrum by maximizingspectral efficiency with its continuous tuning. Second, it reduces filter cost and space requirements while increasing reliability by eliminating increasingly complex filter banks. This will result in smaller, cheaper and more dependable phones for consumers, which will help drive industry growth. Third, the results of this project will deliver Smartphone GPS accuracy rivaling commercial units, as well as enabling protection of GPS-dependent infrastructure against inadvertent or intentional disruption. Fourth, it will enable precise, jamming resistant GPS navigation by aerial drones used by first responders, homeland security and the military, helping prevent crashes that place people at risk.

这一小型企业技术转移研究(STTR)第二阶段项目将扩展线性干扰延迟效应滤波器的基础科学，为所有类型的射频接收器和仪器实现超宽带可调射频滤波器。它还将扩展实现集成电路等过滤器的工程科学。此外，其失真过滤方面将实现信号不可知的自适应消除宽带和带内干扰，以实现抗干扰应用，并提高消费者的信号质量。更广泛的影响/商业潜力是，它将有助于实现国家目标，即通过不断调谐最大化频谱效率来扩大射频频谱的使用范围。其次，它通过消除日益复杂的滤波器组，降低了滤波器成本和空间要求，同时提高了可靠性。这将为消费者带来更小、更便宜、更可靠的手机，这将有助于推动行业增长。第三，该项目的结果将提供与商业单位相媲美的智能手机GPS精度，并能够保护依赖GPS的基础设施免受无意或故意中断。第四，它将使急救人员、国土安全部和军方使用的无人机能够进行精确的、抗干扰的GPS导航，有助于防止将人置于危险境地的坠机事件。
