9979400ScharfAn integrated program of research is proposed for exploiting all available modes of diversity in the wireless channel. This requires the development of novel antennas for transmitting in diverse modes, digital receivers for exploiting these modes, and dynamic resources allocations for assigning them. The primary challenges in this research are to manage and exploit the complex and time varying nature of the wireless communication channel, while meeting the power and bandwidth constraints of mobiles, base stations and networks. Hence, the work emphasizes integration of digital receivers for multiaccess communication with smart antennas and dynamic resource allocation. The smart antenna excites the temporal, spatial, and polarizational modes in the wireless channel. The multiuse receiver uses these modes to decode mobile users and to estimate channel parameters, which are used by the dynamic resource allocator to provide the required QoS to end users.The design of a high frequency (e.g., 30 Ghz), high bandwidth radiating and receiving antenna which is agile in space, time, and polarization will involve numerical modeling, device construction, and testing of a prototype, based on prior experience with millimeter wave lens antennas. The design of multiaccess receivers which exploit available degrees of freedom will be based on actual device characteristics and on realistic scattering models for the channel. These receivers will be designed and implemented in reduced dimension subspaces. These subspaces are generated by resolving the real channel into a parallel combination of virtual diversity channels, using a special canonical space-time coordinate system. The designs will be evaluated using the software radio testbed currently under development at Eurecom.. The innovative aspect of the proposed dynamic network allocation work is the shared use of information at the physical and network layers to jointly optimize the use of channel and network resources for ensuring QoS. Dynamic resource allocation will exploit all the channel modes made available by the antennas and receivers. Estimates of signal to interference plus noise ratio (SINR) and bit error rate (BER) will be shared between the physical and network layers to dynamically allocate power and bandwidth across different channel modes, while keeping signaling and receiver complexity manageable. This integrated research program will influence the conception, development, and implementation of future wireless communication networks.A key element of this project is the integration of student and faculty research activities at three universities: the University of Wisconsin, the University of Colorado, and Eurecom in France, the later a recipient of an IEEE Education Award for its innovative integration of mobile wireless, multimedia, and networking. The likelihood of success I this collaborative program is high, because working relationships between the three schools have been established through prior visits, sabbaticals, and collaborations.The management plan is built around regular visits between laboratories at the participating schools, and joint advising of students working at technology boundaries. The integrated perspective developed in this research program will be incorporated into a new undergraduate wireless communication laboratory, a graduate colloquium course, and a wireless communication reading course. This work will impact the content of existing courses in communications, signal processing, networks, antennas, and electromagnetics.***

提出了9979400scharfan集成研究计划，用于利用无线渠道中所有可用的多样性模式。 这就需要开发新的天线，用于以不同的模式传输，以利用这些模式的数字接收器以及用于分配它们的动态资源分配。 这项研究的主要挑战是管理和利用无线通信渠道的复杂和时间变化的性质，同时满足手机，基站和网络的功率和带宽约束。 因此，这项工作强调了数字接收器与智能天线和动态资源分配的多通信通信的集成。 智能天线在无线通道中激发了时间，空间和极化模式。 The multiuse receiver uses these modes to decode mobile users and to estimate channel parameters, which are used by the dynamic resource allocator to provide the required QoS to end users.The design of a high frequency (e.g., 30 Ghz), high bandwidth radiating and receiving antenna which is agile in space, time, and polarization will involve numerical modeling, device construction, and testing of a prototype, based on prior experience with millimeter wave镜头天线。 利用可用自由度的多通用接收器的设计将基于实际设备特征和频道的现实散射模型。 这些接收器将在缩小的尺寸子空间中设计和实现。 这些子空间是通过使用特殊的规范时空坐标系解决虚拟多样性通道的平行组合来生成的。 设计将使用当前在Eurecom开发的软件无线电测试台进行评估。拟议的动态网络分配工作的创新方面是在物理和网络层上共享信息，以共同优化使用渠道和网络资源来确保QoS的使用。 动态资源分配将利用天线和接收器提供的所有通道模式。 信号与干扰加噪声比（SINR）和位错误率（BER）的估计值将在物理和网络层之间共享，以在不同的通道模式下动态分配功率和带宽，同时保持信号传导和接收器的复杂性可管理。 该综合研究计划将影响未来无线通信网络的概念，发展和实施。该项目的关键要素是在三所大学中的学生和教职研究活动的整合：威斯康星大学，威斯康星大学，法国大学的欧洲大学，后来是IEEE教育奖，以获得IEEE教育奖，以促进其创新的无线，多重元素和网络的创新整合。 成功的可能性I这个协作计划很高，因为这三所学校之间的工作关系是通过先前的访问，放假和合作建立的。该管理计划围绕参与学校的实验室之间的常规访问建立，并共同咨询在技术边界工作的学生。 该研究计划中开发的综合视角将纳入一个新的本科无线通信实验室，研究生座谈会课程和无线通信阅读课程中。 这项工作将影响通信，信号处理，网络，天线和电磁学中现有课程的内容。***
