“…Then, we propose an approximation for very low values of U. Indeed, the values assumed herein are quite conservative compared to the levels reported by the state-of-the-art interference cancellation (combining antenna isolation, analog and digital cancellation), which are close to the noise floor, (see, for instance [41]), so that Here, the term (W 0 + 1) 2 is always greater than 1. Again, by using the approximation for the harmonic mean, this probability can be reduced to After simplifying this multi-fold integral, we obtain the expression in (27).…”

Abstract-In this work, an adaptive scheme for amplify-andforward relaying networks is proposed, which selects a certain transmission mode for each communication process. Depending on the instantaneous channel conditions, one of the following modes is selected: direct transmission with no cooperation, cooperative transmission with half-duplex relaying and maximalratio combining at the destination, or cooperative transmission with full-duplex relaying and maximal-ratio combining at the destination. A three-node network is considered, containing a singleantenna source, a two-antenna relay that is able to implement full-duplex communication, and a single-antenna destination. Energy normalization per block is assumed, so that in those modes using cooperation the system's transmission power is shared between source and relay. The performance analysis is provided in terms of outage probability and energy efficiency. We derive a tight approximate expression in closed form for the outage probability and an approximate expression in integral form for the mean energy consumption. The results show that our scheme outperforms all of transmission modes separately in terms of outage probability, while being more energy efficient than the cooperative transmission modes. Additionally, the asymptotic analysis proves that the proposed scheme achieves full diversity order equal to 2, thus outperforming those schemes with direct transmission or full-duplex cooperation only.Index Terms-Amplify-and-forward, direct link, half duplex, full duplex, adaptive transmission mode, outage probability, relaying networks, energy efficiency.

“…At the base-station, the downlink transmitted signal will leak into its own receiver RF chain (which is referred to as self-interference) and mixed with the received signals from the uplink channel. Advanced analog and digital self-interference cancellation techniques are able to suppress significant amount of this interference [3]. Similarly, at the user terminal, the downlink channel will suffer from the inter-user interference due to the uplink transmission from other users.…”

Abstract-Full-duplex transceivers enable transmission and reception at the same time on the same frequency, and have the potential to double the wireless system spectral efficiency. Recent studies have shown the feasibility of full-duplex transceivers. In this paper, we address the radio resource allocation problem for full-duplex system. Due to the self-interference and interuser interference, the problem is coupled between uplink and downlink channels, and can be formulated as joint uplink and downlink sum-rate maximization. As the problem is non-convex, an iterative algorithm is proposed based on game theory by modeling the problem as a noncooperative game between the uplink and downlink channels. The algorithm iteratively carries out optimal uplink and downlink resource allocation until a Nash equilibrium is achieved. Simulation results show that the algorithm achieves fast convergence, and can significantly improve the full-duplex performance comparing to the equal resource allocation approach. Furthermore, the full-duplex system with the proposed algorithm can achieve considerable gains in spectral efficiency, that reach up to 40%, comparing to half-duplex system.

On performance of analog least mean square loop for self-interference cancellation in in-band fullduplex OFDM systems," in 85th IEEE Vehicular Technology Conference (VTC2017-Spring), 2017, pp. 1-5.On performance of analog least mean square loop for self-interference cancellation in in-band full-duplex OFDM systems AbstractThis paper evaluates the performance of an analog least mean square (ALMS) loop employed to cancel selfinterference in in-band full-duplex (IBFD) orthogonal frequency division multiplexing (OFDM) systems. Cyclostationary analysis is applied to investigate the behavior of the ALMS filter. It is revealed that the performance of the ALMS filter for OFDM systems primarily depends on windowing function rather than pulse shaping as in single carrier systems. It is also noticed that the ALMS loop in OFDM systems provides a much higher level of sel-interference (SI) suppression because OFDM signals lead to reduced the error of the interference channel modelling with the adaptive filter. Simulations are then conducted to verify the theoretical findings.
