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.

下一代移动通信系统预计将提供高数据速率并支持多种服务，包括语音、视频和交互式多媒体。除非以尽可能最有效的方式使用移动通信器中的电池，否则功率限制将成为开发可提供此类服务的通信系统的瓶颈。该项目考虑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器设计和功率控制的统一理论。系统发展这种理论所必需的分析工具和概念正在获得。该项目的目标是最终获得复杂而现实的信道模型的解决方案，从而能够实际实现采用多用户接收器设计和功率控制组合方法的系统的卓越潜力。电池电量的有效使用意味着更持久（无需充电）、更轻，因此更便携、手持式和膝上型通信设备。 努力程度：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努力水平。
