This paper focuses on multi-user full-duplex (FD) systems. When multiple users share the same resources, using FD degrades the sum capacity compared to using half-duplex (HD) because of the inter-user interference (IUI) that arises between two FD users. This factor highlights the need for a good strategy for switching between FD and HD modes. We address(More)
We propose a new method for full-duplex self-interference cancellation. The proposed scheme uses a precoder to align the self-interference channel with orthogonal direction of detection axis. The simulation result shows that the proposed RP-SIC enhances the average throughput of user equipment compared to the conventional scheme in high residual(More)
In this paper, we investigate the impact of outdated channel state information (CSI) on the channel capacity of an opportunistic relaying system in conjunction with adaptive transmission techniques. We derive the closed-form expressions of the channel capacity and its associated outage probability for four adaptive transmission techniques: (1) optimal rate(More)
