Abstract

This paper researched the energy efficiency optimization of simultaneous wireless information and power transfer(SWIPT) in heterogeneous small cellular networks. In order to maximize the energy efficiency of the downlink cellular system, it jointly optimized the splitting ratio of transmit beamforming vector and receive power under both small cellular users' communication quality and the collected energy, and the transmission power of the small cell base station constraints. The problem belonged to the nonconvex optimization problem, which transformed the equivalent problem by the variable substitution, and then used the subgradient iteration algorithm based on the Lagrange multiplier to solve the problem. The results of computer simulation show that the joint optimization algorithm is simple and effective.
