Outage probability in an energy harvesting (EH) block-fading communication system is studied in the finitehorizon online setting. First, the offline version of the problem is considered, and formulated as a mixed integer linear program (MILP). Then, the infinite-horizon online problem (IIL) is considered relaxing the battery constraints. Solutions of these two problems provide lower bounds on the finite-horizon online problem, for which we provide a low-complexity heuristic scheme, called the fixed threshold transmission (FTT) scheme. Numerical results show that the FTT scheme achieves an outage performance close to the MILP lower bound for a wide range of operation regimes, and close to IIL when the EH rate is low. It is also observed that the power allocated by the FTT scheme resembles the optimal offline solution with high probability, despite the lack of information about future channel states and energy arrivals.

Minimum Outage Probability for the Relay Channel under Individual Power Constraints Yüksel Turgut, Ayşe Melda; YÜKSEKKAYA, BARIŞ (2012-07-01) In this letter, minimum outage probability for a fading relay channel is considered for long-term individual power constraints (IPC1) at the source and the relay. By utilizing Lagrange multiplier theory, it is shown that solving the IPC problem is equivalent to solving a weighted sum power constrained (wSPC) problem. Opportunistic decode and forward (ODF), and simplified ODF (SODF) protocol performances are investigated and compared with a lower bound on outage probability, under both individual and sum pow...
Minimum Common Outage Probability for the Broadcast Relay Channel Isikman, Arif Onder; Yüksel Turgut, Ayşe Melda (2011-01-01) In this paper the broadcast relay channel (BRC) is studied. In the BRC model, the source communicates with two destinations with the help of a single relay. The minimum common outage probability for four different transmission protocols, direct transmission (DT), multihop (MH), path selection (PS) and link combination with path selection (LCPS) is investigated under long-term power constraint for constant rate transmission. In addition, the epsilon-outage rate region for a fixed common outage probability is...
Total outage capacity of randomly-spread coded-CDMA with linear multiuser receivers over multipath fading channels Ertug, O; Sayrac, B; Baykal, Buyurman; Yucel, MD (2003-07-03) We address in this paper the derivation and analysis of the outage spectral efficiencies achievable with linear multiuser receivers over randomly-spread multipath fading time-varying coded-CDMA channels. The basis of the derivations is the use of non-asymptotic average eigenvalue densities of random cross-correlation matrices. The analysis give important clues on the achievable capacity with linear multiuser receivers under non-ergodic transmission situations.
Asymptotically Throughput Optimal Scheduling for Energy Harvesting Wireless Sensor Networks Gul, Omer Melih; Demirekler, Mubeccel (Institute of Electrical and Electronics Engineers (IEEE), 2018) In this paper, we investigate a single-hop wireless sensor network in which a fusion center (FC) collects data packets from M energy harvesting (EH) sensor nodes. Energy harvested by each node is stored without battery overflow and leakage at that node. The FC schedules K nodes over its mutually orthogonal channels to receive data from them in each time slot. The FC knows neither the statistics of EH processes nor the battery states of nodes. The FC solely has information on consequences of previous transmi...
An Adaptive-Iterative Nonlinear Interference Cancellation in Time-Varying Full-Duplex Channels Kurt, Anıl; Salman, Murat Babek; Saraç, Uğur Berkay; Güvensen, Gökhan Muzaffer (2022-01-01) In this paper, first, the sensitivity of traditional Full-Duplex (FD) communication systems to time variation in the self-interference (SI) channel is demonstrated via performance analysis. It is seen that conventional schemes are not capable of providing efficient operation regarding practical concerns such as spectral efficiency, SI channel aging and learning accuracy, and the contamination of signal-of-interest (SoI). Then, in regard to the aforementioned concerns, a practical FD operation together with ...
