Cooperative relaying refers to a technique that allows the source to transmit its messages to the destination via the relaying of multiple cooperative partners and exploits the spatial diversity gains inherent in multiuser wireless systems. In this work, we examine cooperative networks with cooperative and malicious relays and determine the optimal behavior for both kinds of relays using a game-theoretic...
Physical layer multicasting with opportunistic user selection and optimized space-time transmission is examined in this work. We consider a multi-antenna downlink scenario where a multi-antenna base-station transmits common information to a given set of users, each with a single receive antenna. In the past, most existing multi-antenna multicasting solutions have been restricted to spatial multiplexing...
