摘　　要：无线信息和能量同传技术(SWIPT)可降低网络中能量的消耗,延长网络中能量消耗设备的使用寿命。该研究对象为发送端发送波束成型信号与用户进行通信,接收端采用功率分配器进行信号分开,分别进行信息和能量的收集,一部分信号流用于能量集,一部分信号流用于信息解调,通过运用波束成型技术,实现系统最小化发送功率,提高系统的吞吐量。同时,利用半正定松驰技术和S程序将该非凸问题转化为一个半定规化问题。最后,通过仿真验证算法,仿真结果证明基于无线信能同传技术的波束成型系统的正确性和合理性。Simultaneous wire-less information and power transfer(SWIPT) can reduce energy consumption in the network and extend the lifetime of the energy consuming devices in the network. The object of this study is to transmit beam-forming signals to communicate with users. The receiver uses power divider to separate the signals and collect information and power respectively. A part of the signal flow is used for energy collection, and a part of the signal flow is used for information demodulation. By using beamforming technology, the transmission power of the system is minimized and the sum rate of the system is improved.At the same time, the non-convex problem is transformed into a semi-definite programming(SDP) problem by using the semi-definite relaxation(SDR) technique and S-program.Finally, simulation results show that the beamforming system based on wireless communication and simultaneous interpreting is correct and reasonable.
