Selective Relay-Activation for Conditional DF Relaying

IEEE Transactions on Communications, 2014
This paper considers a conditional decode-and-forward (DF) based cooperative system where a source (S) with multiple (M) antennas transmits information to a single-antenna destination (D) with the help of multiple (L ≤ M-1) single-antenna relays ({R_i}).
