| Abstract(in English) | In this paper, we investigate a secure beamforming (BF) design for cell-free massive multiple input mul tiple output (CF-mMIMO) systems composed of a set of legitimate user equipments (LUEs) and eavesdropping UEs (EUEs), where each LUE is equipped with a different number of antennas and each EUE is equipped with the same number of antennas as the LUE in target. We propose an iterative algorithm to design a TX BF that maximizes a total secrecy capacity and enable secure communications even when the LUE’s channel matrix and EUE’s channel matrix are highly correlated. Simulation results demonstrate the superior performance of our proposed BF design to the conventional maximum ratio combining (MRC) and minimum mean square error (MMSE) BF methods in terms of the system sum secrecy capacity. |
