Quality of service assurance in multi-antenna relay-assisted networks

Joint signal‐to‐noise ratio‐based transceiver design for amplify‐and‐forward multiple‐input multiple‐output relay systems

“…One is an iterative algorithm, and the other is an approximated closed-form solution with lower complexity. Similar works about transceiver design can be found in [21][22][23][24][25][26][27].…”
