This Small Business Innovation Research (SBIR) Phase I project aims at developing advanced analog nonlinear algorithms and circuits for mitigation of in-band noise and interference, especially that of manmade origin, affecting various signals of interest and limiting the performance of the affected devices and services. Manmade noise, unintentional as well as intentional, is a ubiquitous and rapidly growing source of interference with various electronic devices, systems, and services, harmfully affecting their physical, commercial, and operational properties. This noise comes from a magnitude of various sources such as mutual interference of multiple devices combined in a system (for example, a smartphone equipped with WiFi, Bluetooth, GPS, and many other devices), electrical equipment and electronics in home and office, dense urban and industrial environments, increasingly crowded wireless spectrum, and intentional jamming. The proposed nonlinear algorithms and circuits, Adaptive Nonlinear Differential Limiters (ANDLs), have many significant advantages over existing filtering solutions, providing capabilities that cannot be replicated by linear filtering devices and systems. ANDLs also enable elegant and inexpensive real-time solutions to the manmade interference problems that may be used in addition, or as a low-cost alternative, to the state-of-art interference mitigation methods.The broader impact/commercial potential of this project is in its ability to advance scientific and technological understanding of the problems caused by manmade interference, as the proposed ANDL algorithms and circuits enable a variety of simplified and inexpensive real-time solutions to these problems, further enhancing the societal and commercial impact of the proposed technology. ANDLs are intended to be fully compatible with existing linear devices and systems, and to be used in addition, or as a low-cost alternative, to the state-of-art interference mitigation methods. When incorporated into existing devices and/or systems as integrated circuit ANDL cells, ANDLs may be widely deployed, in a sustaining as well as disruptive manner, to meet the increasing demand for reducing manmade noise and leading to improvements in physical, commercial, and operational properties of those devices, and the systems and services that incorporate and use the improved devices. This will benefit a wide range of applications in high revenue industries such as, for example, consumer electronics, medical, industrial, and defense electronics, and industrial, consumer, and military communication devices and services.

该小型企业创新研究（SBIR）第一阶段项目旨在开发先进的模拟非线性算法和电路，以减轻带内噪声和干扰，特别是人为来源，影响各种感兴趣的信号并限制受影响设备和服务的性能。人为噪声，无论是无意的还是有意的，都是对各种电子设备、系统和服务的普遍且快速增长的干扰源，对它们的物理、商业和操作特性造成有害影响。这种噪声来自各种源的大小，例如组合在系统中的多个设备（例如，配备有WiFi、蓝牙、GPS和许多其他设备的智能手机）的相互干扰、家庭和办公室中的电气设备和电子设备、密集的城市和工业环境、日益拥挤的无线频谱以及故意干扰。所提出的非线性算法和电路，自适应非线性差分限幅器（ANDL），有许多显着的优势，现有的滤波解决方案，提供的能力，不能复制的线性滤波设备和系统。ANDL还可以实现对人为干扰问题的优雅和廉价的实时解决方案，这些解决方案可以作为最先进的干扰缓解方法的补充或低成本替代方案使用。该项目更广泛的影响/商业潜力在于它能够促进对人为干扰引起的问题的科学和技术理解，因为所提出的ANDL算法和电路使得能够对这些问题实现各种简化且廉价的实时解决方案，从而进一步增强所提出的技术的社会和商业影响。ANDL旨在与现有的线性设备和系统完全兼容，并且除了现有技术的干扰抑制方法之外或作为低成本的替代方法使用。当作为集成电路ANDL单元被并入现有设备和/或系统中时，ANDL可以以持续以及破坏性的方式被广泛部署，以满足对减少人为噪声的日益增长的需求，并导致这些设备以及并入和使用改进的设备的系统和服务的物理、商业和操作属性的改进。这将有利于高收入行业中的广泛应用，例如消费电子、医疗、工业和国防电子，以及工业、消费和军事通信设备和服务。
