With the explosion of wireless devices, spectrum is becoming a scarce resource that wireless systems fiercely compete for. To ensure that future civilian and military systems, ranging from connected Internet of Things (IoT) devices to battlefield ad-hoc networks, continue to support services with growing quality, systems must evolve beyond the traditional spectrum licensing model and towards an intelligent spectrum sharing paradigm, in which networks nodes collaborate to efficiently share the spectrum. This radical paradigm shift requires the integration of the latest machine learning advances with the more recent progress in software defined radio, in order to endow wireless devices with the intelligence and agility necessary to realize the vision of efficient unsupervised spectrum sharing. The proposed research aims at addressing this fundamental issue, and will offer ample opportunities to provide interdisciplinary training of students at the intersection of machine learning and communications engineering.The project envisions a paradigm shift in radio design, which will intertwine agile communications engineering techniques with advanced machine learning algorithms to fuse the traditional physical-layer and link layers into a "collaboration layer". Specifically, the approach comprises three key elements: (1) a multi-carrier modulation format at the physical layer that provides the required agility to react to interfering signals; (2) a high-performing modulation recognition software that exploits the latest advances in deep learning and convolutional neural networks to accurately classify the radio frequency signals in the environment; and (3) a decision module exploiting the latest advances in regret minimization online algorithms to achieve high exploration versus exploitation performance in the wireless environment.

随着无线设备的爆炸式增长，频谱正成为无线系统激烈竞争的稀缺资源。为了确保未来的民用和军用系统（从物联网（IoT）设备到战场自组织网络）继续支持质量不断提高的服务，系统必须超越传统的频谱许可模式，并朝着智能频谱共享模式发展，其中网络节点协作以有效共享频谱。这种彻底的范式转变需要将最新的机器学习进展与软件定义无线电的最新进展相结合，以赋予无线设备实现高效无监督频谱共享愿景所需的智能和灵活性。该项目旨在解决这一基本问题，并将为学生提供充分的机会，在机器学习和通信工程的交叉点提供跨学科的培训。该项目设想了无线电设计的范式转变，这将使敏捷的通信工程技术与先进的机器学习算法相结合，将传统的物理层和链路层融合为“协作层”。具体而言，该方法包括三个关键要素：（1）物理层的多载波调制格式，提供对干扰信号做出反应所需的灵活性;（2）高性能调制识别软件，利用深度学习和卷积神经网络的最新进展，对环境中的射频信号进行准确分类;以及（3）决策模块，其利用后悔最小化在线算法的最新进展来实现无线环境中的高探索与利用性能。
