International Postdoctoral Fellows Program: Adaptive Multi-User Receivers for Fading and Time-Dispersive Communication Channels

9403734 Mitra 该奖项属于国际初级研究员和博士后研究员计划，该计划使美国科学家和工程师能够在国外经过证明卓越的研究中心进行三到十二个月的研究。 该项目的奖项提供了联合研究以及使用国外独特或互补的设施、专业知识和实验条件的机会。 该奖项将支持 Urbashi Mitra 博士与法国 EURECOM 研究所的 Pierre Humblet 和 Dirk Slock 教授进行为期 12 个月的博士后研究访问。 无线通信网络被提议用于固定站点源，例如局域网。 共享无线电信道需要开发和分析来自多个用户的信号的高效接收器。 考虑到带宽效率、无线电频谱分配、接收器技术复杂性、服务质量和隐私问题，这些新型多用户接收器必须协同运行。 本研究的目的是将新提出的多用户接收器增强为自适应结构。 提出了进一步的扩展以适应来自时间色散通信信道的干扰。 还将研究创建无需使用训练信号即可运行的自适应多用户接收器的可能性。 ***

9403734 Mitra This award is under the International Junior Investigator and Postdoctoral Fellows Program, which enables U.S. scientists and engineers to conduct three to twelve months of research abroad at research centers of proven excellence. The program's awards provide opportunities for joint research, and the use of unique or complementary facilities, expertise and experimental conditions abroad. This award will support a twelve-month postdoctoral research visit by Dr. Urbashi Mitra to work with Professors Pierre Humblet and Dirk Slock at Institut EURECOM in France. Wireless communication networks are proposed for fixed site sources such as local area networks. The shared radio channel necessitates the development and analysis of efficient receivers for signals from a multitude of users. These new multi-user receivers must operate synergistically vis a vis concerns for bandwidth efficiency, radio spectrum allocation, the receiver technology complexity, quality of service and privacy issues. The object of the proposed research is to augment newly proposed multi-user receivers to be adaptive structures. Further extensions are proposed to accommodate interference from time-dispersive communication channels. The possibility of creating adaptive multi-user receivers that operate without the use of training signals will also be investigated. ***
