TL;DR: In this paper, a tractable analysis framework is proposed to evaluate the reliability and the security of wireless-powered decode-and-forward (DF) multi-relay networks with nonlinear energy harvesters, in-phase and quadrature-phase imbalance (IQI) and channel estimation errors (CEEs).

TL;DR: This paper investigates the performance of cooperative non-orthogonal multiple access (NOMA) systems, where one near user works as a decode-and-forward (DF) full-duple (FD) or half-duplex (HD) relaying to help far user, and confirms that the use of the direct link overcomes the zero diversity order of far NOMA user inherent to FD relaying.

TL;DR: A novel algorithm for obtaining a sub-optimal solution based on the many-to-many two-sided matching game with externalities is proposed and it is proved that it converges to the two- sided exchange stability within a limited number of iterations.

TL;DR: A practical algorithm, based on UE selection, successive convex approximation and semi-definite relaxation approach, is proposed to solve the unavailability of complete channel state information in ultra-dense cloud radio access networks with guaranteed convergence.

TL;DR: Numerical results corroborate the authors’ analysis and show that the DS policy performs the best in terms of both outage probability and throughput among the proposed policies, and the TDBC protocol achieves lower outage probability than the MABC protocol.
