Two-phase and three-phase decode-and-forward schemes with network coding for the two-way (bidirectional) relay channel with Rayleigh-fading are considered. All nodes are half-duplex constrained. Closed form expressions of the outage probability for the two-phase scheme and the three-phase scheme with symmetric rate and time-allocation with Gaussian distributed channel inputs are derived, necessary...
Current broadband wireless networks are characterized by large cell sizes. Yet, even in advanced networks, users on the cell edge will face relatively low Signal-to-Interference-plus-Noise-Ratio (SINR). An attractive solution for this problem is provided by multi-hop technologies. In this paper, we consider the performance of full duplex Amplify-and-Forward (AF) and half duplex Decode-and-Forward...
Relaying is one of the most important novel elements in 3GPP LTE-Advanced study item. It promises to offer significant gain for system capacity or coverage depending on the deployment prioritization. In this paper, we investigate the feasibility of relay node deployments in terms of system throughput and cell coverage area extension as compared to pico node deployments and traditional homogeneous...
