Adaptive power allocation in cooperative OFDM transmission with three-hop DF relaying

Adaptive power allocation subject to the total power constraint in an end-to-end cooperative orthogonal frequency Division multiplexing (OFDM) system is studied, with the optimal power allocation in terms of maximizing the sum transmission Rate being derived. The conventional two-hop system model is...
