A cross-layer secure communication scheme for multiple input multiple output (MIMO) system based on spatial modulation (SM) is proposed in this paper. The proposed scheme combined the upper layer stream cipher with the distorted signal design of the MIMO spatial modulation system in the physical layer to realize the security information transmission, which is called cross-layer secure communication...
The antenna subarray formation (ASF) is a promising technique for multiple-input multiple-output (MIMO) receiver. For MIMO wiretap channels, we employ the ASF matrix at the legitimate receiver and propose new alternative optimization (AO) scheme which jointly designs transmit covariance matrix and ASF matrix to maximize the secrecy capacity. Simulation results have shown that the proposed ASF schemes...
In this paper, we consider a transmit precoder design for multiple-input-multiple-output (MIMO) decode-and-forward (DF) half-duplex two-hop relaying system consisting of one transmitter, one relay, one information-decoding (ID) receiver, and one energy harvesting (EH) receiver, where all nodes are equipped with more than one antenna. Our objective is to maximize data rates of this system by designing...
This paper proposed a MIMO cross-layer precoding secure communications via pattern controlled by higher layer cryptography. By contrast to physical layer security system, the proposed scheme could enhance the security in adverse situations where the physical layer security hardly to be deal with. Two One typical situation is considered. One is that the attackers have the ideal CSI and another is eavesdropper's...
