摘　　要：移动通信无线传输技术(Radio Transmission Technology,RTT)的关键技术是多址技术和复用技术,非正交多址技术是5G技术的核心。5G技术已不在单纯地追求频谱效率和传输速率,而是与软件化、智能化和云传输等相融合。所以,在确保用户公平性的前提下上实现信道容量最大化成为5G技术的瓶颈之一。论文针对通信系统模型,将注水功率分配算法应用到非正交多字技术功率复用中,使信道容量最大化和用户功率分配最优化。将注水功率分配算法、平均功率算法和比例公平调度算法进行深入比较分析,并进行仿真验证,为5G时代大容量、多用户的通信系统提供一种优化的功率复用算法。The core of the radio transmission technology is the multiple access technology and multiplexing technology. The non orthogonal multiple access technology （NOMA） is the focus attention of the comijust improving efficiency and expanding the spectrum , but focusing on the combination of software , cloud transmission , in-telligent ,and so on So one of the bottlenecks of 5G technology is maximize the capacity on the base of keeping the user fair-ness. The paper , on the base of the communication system model applies the water-filling power allocation algorithm to pow-er reuse technology. tt figures out the optimal allocation power to maximize the channel capacity and ensucation of power about user fairness. tt takes comparison and simulation and validation among the Water flooding algorithm ,the Average power algorithm and the Proportional average scheduling algorithm. Themeet the needs of large capacity multi-user of the 5G technology in the future.
