Claude Shannon?s ?A Mathematical Theory of Communication? is the landmark event that paved the way for the development of modern communication systems. Shannon analyzed the fundamental redundancy that must be added to data in order to achieve reliable communication in the presence of noise. Since then his vision has guided the practical design of virtually all aspects of modern communication systems such as forward error correction, spectrally-efficient communication, multiuser and inter-symbol interference, multiple-antenna systems, opportunistic communication, and joint compression/transmission. However, while feedback is present in virtually all modern communication systems, the field of information theory has had relatively little impact on how feedback is employed in practice. The proposed work will advance knowledge by developing a more complete understanding of how feedback should be employed in communication systems and what quantitative improvements in delay, complexity, and transmitted power one can expect from its effective use, under realistic delay constraints such as those found in high-speed wireless data. In summary, the successful completion of the project is expected to contribute new mathematical tools, designs, viewpoints, and models to the field of information theory.The goal of this research is to bring the insight, design guidance, and performance bounds for which information theory is known to bear on the design of systems with feedback. By providing new design principles and feedback codes, this research has the potential not only to advance basic science but also to improve the efficiency and reliability of our communications infrastructure, including consumer technology such as WiFi and smartphones. Given the proliferation of personal communication devices, such improvements would augment the efficiency with which crucial resources such as energy and radio frequency bandwidth are currently utilized.

克劳德·香农（Claude Shannon）？是地标活动为开发现代通信系统铺平了道路。香农分析了必须添加到数据中的基本冗余，以便在存在噪声的情况下实现可靠​​的通信。从那时起，他的愿景几乎指导了现代通信系统的几乎所有方面的实践设计，例如远期误差校正，频谱效率的通信，多源和符号间干扰，多 - 安特纳纳系统，机会性交流以及关节压缩/传输。但是，尽管几乎所有现代通信系统中都存在反馈，但信息理论领域对在实践中使用的反馈的影响相对较小。 拟议的工作将通过对通信系统中应采用反馈的方式进行更完整的了解，以及在现实的延迟限制下，例如在高速无线数据中发现的延迟，复杂性和传播能力，可以从其有效使用中期望的延迟，复杂性和传播能力方面的定量改进来提高知识。总而言之，预计该项目的成功完成将为信息理论领域贡献新的数学工具，设计，观点和模型。这项研究的目的是带来洞察力，设计指导和性能范围，以此为信息理论所涉及的信息理论所涉及的系统设计。通过提供新的设计原理和反馈代码，这项研究不仅有可能提高基础科学，而且有可能提高通信基础架构的效率和可靠性，包括WiFi和智能手机等消费者技术。鉴于个人通信设备的扩散，此类改进将提高目前利用能源和射频带宽等关键资源的效率。
