US-France Cooperative Research: Exchange on Adaptive Telecommunication Engineering

这项为期三年的美法无线通信合作项目涉及康奈尔大学和法国国家电信研究所的学生和研究人员。美国的C. Richard Johnson和法国的Phillip Regalia领导了这个关于宽带电信接收机的理论、设计和教学的合作项目。随着通信系统变得复杂，硬件的进步允许在电信接收器中使用更复杂的算法，这些系统将对新兴应用变得更加关键。研究人员将讨论四个主题：(1)自适应多载波均衡；(2)超宽带接收机；(3)涡轮均衡；均衡器初始化策略。研究人员在控制，信号处理和通信应用的自适应系统理论方面具有互补的专业知识。他们的专门知识将用于研究宽带接收机子系统的相互作用，如同步、均衡和编码。法国在联合编码和均衡方面的专长有潜力适应美国正在开发的无线个人区域网络。同样，美国在多载波和超宽带方面的专长可以应用于解决欧洲本地无线链路频谱频段效率低下的问题。该奖项代表了美国方面向美国国家科学基金会和法国国家科学研究中心（CNRS）联合提出的建议。美国国家科学基金会将支付美国研究员和研究生的旅费和生活费。CNRS将支持法国研究人员和研究生访问美国。

0233127JohnsonThis three-year award for US-France collaboration in wireless telecommunications involves students and researchers at Cornell University and the French National Institute for Telecommunications. C. Richard Johnson in the US and Phillip Regalia in France lead this cooperative project on the theory, design, and pedagogy of broadband telecommunications receivers. As communication systems become sophisticated and hardware advances allow for more complex algorithms in telecommunications receivers, these systems will become more critical to emerging applications. The investigators will address four topics: (1) adaptive multi-carrier equalization; (2) ultra wideband receivers; (3) turbo equalization; and (4) equalizer initialization strategies. The investigators have complementary expertise in adaptive system theory for control, signal processing and communications applications. Their expertise will be used in studies of the interplay of broadband receiver subsystems such as synchronization, equalization and coding. The French expertise in joint coding and equalization has potential for adaptation to wireless personal area networks under development in the US. Similarly, US expertise in multi-carrier and ultra wideband could be applied to problems of inefficient spectral band in local wireless links in Europe.This award represents the US side of joint proposals to the NSF and the French National Center for Scientific Research (CNRS). NSF will cover travel funds and living expenses for the US investigator and graduate student. CNRS will support the visits of the French researchers and graduate students to the United States.
