ITR：协作研究：(EVS+NHS)-(INT+DMC)：‘快速铜缆’：宽带接入网络在频率、幅度、空间和时间方面的资源动态优化普林斯顿大学John Cioffi，斯坦福大学Alexander Fraser，弗雷泽研究奖0427677摘要宽带接入是电信的商业和技术未来。接入链路上的较高数据速率支持任何或所有视频、数据和语音/音频信号。人们普遍认识到，向大多数美国家庭部署无处不在、强大的宽带接入服务的能力对于经济繁荣、充满活力的公民社会和国土安全至关重要。这个“快速铜”项目的目标是帮助建立一个工程基础，将宽带信息服务带给每个有电话线的人，包括生活在农村和贫困地区的人。这可以通过大幅提高现有铜厂接入网络的速率和可靠性来实现。因此，美国宽带信息接入的公平性将得到加强。为实现这一目标，研究活动有两条主线：(A)动态和联合优化频率、幅度、空间和时间(FAST)资源，以克服衰减和串扰瓶颈；(B)在双绞线网络的多用户环境中集成通信、联网、计算、建模和分布式信息管理。在物理层算法以及网络架构和协议方面都在追求创新。特别是，动态频谱管理是一门多用户方法的科学，用于动态地将接入网络自适应地调整到特定情况，以提高速率和实现可行性。这项提案有将研究与教育相结合的主要活动。它还促进了与业界的密切合作，分析具有高度价值的经验数据，并通过广泛的实验室测试验证研究结果。

ITR: COLLABORATIVE RESEARCH: (EVS+NHS)-(int+dmc): 'FAST Copper': Dynamic Optimization of Resources in Frequency, Amplitude, Space, and Time for Broadband Access NetworksMung Chiang, Princeton UniversityJohn Cioffi, Stanford UniversityAlexander Fraser, Fraser ResearchAward 0427677AbstractBroadband access is the commercial and technical future of telecommunications. Higher data rates on access links enable any or all of video, data, and voice/audio signals. It is widely recognized that the ability to deploy ubiquitous, robust, broadband access services to the majority of U.S. households is vital to economic prosperity, a vibrant civil society, and homeland security. The goal of this 'FAST Copper' project is to help build an engineering foundation to bring broadband information services to everyone with a phone line, including people who live in rural and less-privileged areas. This can be achieved by substantially enhancing the rate and reliability of the existing copper plant access network. Equity of broadband information access in the U.S. will be enhanced as a result. There are two threads of research activities towards this goal: (a) dynamic and joint optimization of resources in Frequency, Amplitude, Space, and Time (FAST) to overcome the attenuation and crosstalk bottlenecks, and (b) integration of communication, networking, computation, modeling, and distributed information management in the multi-user environment of twisted pair networks. Innovations in both physical layer algorithms and network architectures and protocols are pursued. In particular, Dynamic Spectrum Management, a science of multi-user methods for adaptively tuning an access network to specific situations dynamically, is investigated for rate improvements and implementation viability. This proposal has major activities integrating research with education. It also facilitates close collaboration with industry in analyzing highly valuable empirical data and validating research results through extensive lab tests.
