Power allocation for amplify and forward MIMO-OFDM relay network
Ngoc Van Nguyen, Fuqiang Liu, Ping Wang · 2010
Multiple-input multiple-out (MIMO), orthogonal frequency division multiplexing (OFDM) and relay technology have been considered as the key technologies in the next wireless networks. In this paper we propose a joint power allocation for amplify and forward MIMO-OFDM relay network at the source and relay nodes, the simulation results show that the system performance can be improved greatly.
