中文摘要： 随着宽带无线通信和移动互联网的快速发展，人们对高速无线数据传输业务的需求日益迫切。然而，现有的移动通信系统无法为偏远山区移动用户提供高质量、低成本无线宽带业务。因此，提出适合于偏远山区未来移动通信系统尤为重要。本项目构建一种以认知无线电和MIMO为技术基础的认知无线电MIMO广播信道(CR MIMO-BCs)通信系统，能够满足未来偏远山区移动用户业务需求。功率控制与分配是实现这种通信系统的关键技术。本项目拟开展CR MIMO-BCs功率控制与分配算法研究与实现，主要研究内容包括：基于博弈论的CR MIMO-BCs功率控制与分配算法研究、基于多条件约束的CR MIMO-BCs功率分配算法研究以及CR MIMO-BCs联合功率控制的自适应信道功率分配算法研究。该研究得到的功率控制与分配算法复杂度低，易于实现，有助于推动功率控制与分配技术在CR MIMO-BCs系统中的实际应用。

英文摘要： With the rapid development of broadband wireless communications and mobile internet, There is an increasingly urgent demand for high-speed wireless data transmission services. However, the existing mobile communication systems cannot provide high-quality and low-cost wireless broadband services for mobile users in remote mountainous areas. Therefore, it is particularly important to propose new mobile communication systems that are suitable for future communications in remote mountainous areas. This project proposes to build a cognitive radio multiple-input multiple-output broadcasting channels (CR MIMO-BCs) communication system based on cognitive radio and MIMO technologies. The system is able to meet the future business needs of mobile users in remote mountainous areas. Power control and power allocation are the key techniques for implementing CR MIMO-BCs communication systems. This project will investigate and implement power control and power allocation algorithms for CR MIMO-BCs. We will focus on the study of the following three aspects: 1) power control and allocation algorithms for CR MIMO-BCs based on game theory, 2) power control and allocation algorithms for CR MIMO-BCs based on multiple condition constraints, and 3) joint power control and adaptive power allocation algorithms for CR MIMO-BCs.
