In this letter, we investigate the outage performance of two-way relaying system based on the fixed gain amplify-and-forward protocol and asymmetric traffic requirements. At first, we propose a three-step scheme to obtain the channel state information with a low-complexity relay. Then, the exact expression of system outage performance is derived and we further investigate the asymptotic performance...
In this paper, we study the joint resource allocation for the multi-destination amplify-and-forward relay network with direct source-to-destination links based on orthogonal frequency division multiplexing (OFDM) transmission. We aim to maximize the sum rate by jointly optimizing power allocation, subcarrier pairing, user assignment and transmission mode classification subject to the individual power...
This paper proposes a novel sub-optimal transmit antenna selection (TAS) strategy for non-regenerative half-duplex MIMO relay channel. While antenna selection is a sub-optimal form of beamforming, it still enjoys the advantage of tractable optimization and low feedback overhead. The diversity order of this proposed strategy is derived to prove that it can achieve the full diversity order as the optimal...
