The relay selection and power optimization of multi-relay cooperative communication network under a joint sum power constraint was considered. A low complexity lay selection and power allocation algorithm was also pro-posed in amplify-and-forward cooperative network aiming at minimizing the probability of system outage. In this scheme. optimal power allocation among source and relay n... https://www.sukrensi.com/flash-offer-ILOOTPAPERIE-Washi-Tape-best-find/
