Future generation mobile communication systems are expected to provide high data rates and support a wide variety of services including voice, video and interactive multimedia. Unless batteries in the mobile communicators are used in the most efficient possible manner, power limitations will become a bottleneck in developing communication systems that can provide such services.This project considers the problem of making highly efficient use of power in wireless multiple-access communications. To this end, a unified theory of multiuser receiver design and power control is being sought. The analytical tools and concepts necessary for a systematic development of such a theory are being obtained. The objective of the project is to ultimately obtain solutions for complex and realistic channel models that will make it possible to practically realize the superior potential of systems that adopt a combined approach to multiuser receiver design and power control. Efficient use of battery power translates into longer lasting (without recharge), lighter, and hence more portable, hand-held and lap-top communication devices.Level of Effort:At the recommended level of support, The PI will make every attempt to meet the original scope and level of effort of the project.

下一代移动的通信系统期望提供高数据速率并支持包括语音、视频和交互式多媒体的各种各样的服务。如果不能最有效地利用移动的通信机中的电池，则功率限制将成为开发能够提供这种服务的通信系统的瓶颈。本课题研究在无线多址通信中高效利用功率的问题。为此，正在寻求多用户接收机设计和功率控制的统一理论。正在获得系统地发展这种理论所需的分析工具和概念。该项目的目标是最终获得复杂和现实的信道模型的解决方案，这将使它有可能实际实现系统的上级潜力，采用多用户接收机设计和功率控制的组合方法。电池电源的有效利用转化为更持久（无需充电）、更轻，因此更便携的手持和笔记本电脑通信设备。工作水平：在建议的支持水平下，PI将尽一切努力满足项目的原始范围和工作水平。
