dc.description.abstractMillimeter-wave (mmWave) communication systems are realized to play a key role in next-generation communication systems to achieve high data rate requirements, allowing manifold connected devices and efficient bandwidth utilization. Although mmWave communication has severe degradation problems, security is considered as one of the most important issues. The objective of this study is to analyze and compare the effectiveness of secure communication among the transmitter, legitimate receiver and illegal user using different hybrid precoding and combining algorithms (phase extraction alternate minimizing (PE-AltMin), manifold optimization (MO-AltMin), spatially sparse precoding (SSP) and most recent reported algorithm in the literature). In this study, standard PE-AltMin and MO-AltMin algorithms are also modified in digital baseband domain to achieve better results. The security is achieved in two steps. First, cooperative analog precoder and combiner design algorithms are utilized to get RF precoder and combiner, and then, digital precoder and combiner are attained based on effective baseband digital channel. The simulation studies validate the impact of modified PE-AltMin algorithm that realizes better secrecy rate results than the other hybrid algorithms and ensures the most protected transmission. In simpler words, the utilization of proposed PE-AltMin hybrid algorithm offers the least information leakage towards Eavesdropper than others. (c) 2020 Elsevier B.V. All rights reserved.
