Secure communication with noisy feedback is studied in this correspondence. Unlike the majority of previous research efforts where the eavesdropper's channel state information (CSI)—either instantaneous or statistical CSI, is known by the legitimate users, a joint feedback and artificial noise scheme without any eavesdropper's CSI is proposed. The proposed scheme lets the source and the legitimate...
In recent years, many approaches have been introduced in next generation (5G) wireless cellular networks in response to the demands for higher data rates and broader coverage. In this paper, a novel downlink three-dimensional (3D) beamforming scheme is proposed for the 5G multiuser multiple-input multiple-output (MU-MIMO) system. This scheme separates beams in the so-called elevation domain via base...
To achieve spatial diversity and improve the average bit error probability (ABEP) of Generalized Space Shift Keying (GSSK) in Multiple-Input and Multiple-Output (MIMO) channels with low feedback overhead and computational complexity, we propose a three-step adaptive precoding strategy for single-user GSSK (SU-GSSK) transmission by exploiting the channel state information at the transmitter (CSIT)...
Traditional detection algorithms for frequency selective Orthogonal Frequency Division Multiplexing Vertical-Bell Labs Layered Space-Time system (OFDM-V-BLAST) suffer from high computational complexity. So it's necessary to develop a detection algorithm to minimize the computational complexity and improve BER performance. This paper presents a new reduced-rank detection algorithm based on MMSE Sorted...
