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.
