Half-Duplex AF Relaying: Achievable Rate and Power Allocation Over Fading Channels,ts. The derived approximations are then used not only to compare different amplification coefficients, but also to obtain asymptotically optimal power allocation schemes to maximize the rate or sum rate. Simulation results are finally provided to verify the tightness of the approximations and quantify the gain of the proposed allocation schemes.

Half-Duplex AF Relaying: Error Performance and Precoding,loor area, an optimal class of precoders in terms of diversity and coding gain is developed along with a pragmatic approach to obtain good rotation angles for such class. In the turbo pinch-off region, we demonstrate that a combination of multi-frame precoding and multi-dimensional mapping can be used to approach the capacity of the relay channel.

Full-Duplex AF Relaying: Capacity Under Residual Self-Interference,en analyzed in different high power regions. Specifically, we show that full power at the relay is not necessarily optimal and that the optimal multiplexing gain is .. The conditions under which full-duplex outperforms half-duplex are finally discussed.

Half-Duplex AF Relaying: Achievable Rate and Power Allocation Over Fading Channels,yleigh fading channels. First, a general approach is proposed to obtain tight and simple approximations to the achievable rates in high and low transmission power regions. The proposed approach is applicable to different relaying protocols, and to both the channel-inversion and fixed-gain coefficien
