Diversity-Multiplexing Tradeoffs in MIMO Relay Channels
—A multi-hop relay channel with multiple antenna terminals in a quasi-static slow fading environment is considered. For both full-duplex and half-duplex relays the fundamental di...

Improving wireless physical layer security via cooperating relays
Physical (PHY) layer security approaches for wireless communications can prevent eavesdropping without upper layer data encryption. However, they are hampered by wireless channel c...
