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.

ITR：协作研究：(EVS+NHS)-(int+dmc)：“FAST Copper”：宽带接入网络频率、幅度、空间和时间资源的动态优化Mung Jiang，普林斯顿大学John Cioffi，斯坦福大学Alexander Fraser，Fraser ResearchAward 0427677摘要宽带接入是电信商业和技术的未来。 接入链路上更高的数据速率可实现任何或所有视频、数据和语音/音频信号。 人们普遍认识到，为大多数美国家庭部署无处不在、强大的宽带接入服务对于经济繁荣、充满活力的公民社会和国土安全至关重要。 “FAST Copper”项目的目标是帮助建立一个工程基础，为每个拥有电话线的人提供宽带信息服务，包括生活在农村和贫困地区的人们。 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。 美国宽带信息接入的公平性将因此得到提高。 实现这一目标的研究活动有两条线索：（a）频率、幅度、空间和时间（FAST）资源的动态联合优化，以克服衰减和串扰瓶颈；（b）通信、网络、双绞线网络多用户环境中的计算、建模和分布式信息管理。 追求物理层算法以及网络架构和协议的创新。特别是，动态频谱管理是一门多用户方法科学，用于根据特定情况动态自适应调整接入网络，旨在提高速率和实现可行性。 该提案的主要活动是将研究与教育结合起来。 它还促进与行业的密切合作，分析非常有价值的经验数据并通过广泛的实验室测试验证研究结果。
