Adaptive power allocation for multi-hop regenerative relaying OFDM systems
Xiao Juan Zhang, Yi Gong · 2010
We consider multi-hop decode-and-forward relaying OFDM systems in this paper. All the relay nodes are assumed to be regenerative and working in half-duplex mode. We propose adaptive power allocation (PA) algorithms to maximize the overall system capacity and minimize the system outage probability, respectively. Simulation results show that the proposed algorithms outperform the existing PA algorithms in literature.
