Low-Complexity Transceiver Design for MIMO Broadcast Systems

Robust secure switching transmission in multi‐antenna relaying systems: cooperative jamming or decode‐and‐forward beamforming

“…Some recent works have been proposed to overcome this limitation by taking advantage of multiple antenna systems, e.g. multiple-input multiple-output (MIMO) [3,4], single-input multiple-output (SIMO) [5] and multiple-input single-output (MISO) [6,7] systems. Alternatively, an efficient solution to enhance the legitimate transmission is through cooperative relaying or confusing the eavesdroppers via cooperative jamming (CJ).…”
