Abstract
Considering simultaneous wireless information and power transfer (SWIPT), we investigate robust secure transmission scheme in two-user multiple-input-single-output interference channels, where channel uncertainties are modeled by worst-case model. Our objective is to maximize the worst-case sum secrecy rate under individual transmit power constraints and worst-case energy harvest (EH) constraints. We propose an alternative optimization (AO) based algorithm to solve the robust secure transmission problem, and we can obtain a closed form solution in the process of AO algorithm. Simulation results demonstrate that our proposed robust secure transmission scheme has significant performance gain over the non-robust one.
