Hybrid cognitive Gaussian two-way relay channel: Performance analysis and optimal resource allocation

Joint optimal resource allocation schemes for downlink cooperative cellular networks over orthogonal frequency division multiplexing carriers

“…In particular, authors in [18,19] explored the adaptive power allocation for a 2-hop wireless diversity relay network to maximise the received signalto-noise ratio (SNR) at the destination. Meanwhile, Gunnery et al [20] investigated Gaussian orthogonal relay channels over joint OFDM subchannel and power allocation to improve transmission efficiency. In [21], a centralised utility maximisation framework was studied for a wireless cooperative cellular data network with the ability to relay information to improve the overall network performance.…”
