We develop a novel graph-based trainable framework to maximize the weighted sum energy efficiency (WSEE) for power allocation in wireless communication networks. To address non-convex nature of problem, proposed method consists modular structures inspired by classical iterative suboptimal approach and enhanced with learnable components. More precisely, we propose deep unfolding successive conca...

Fog networks offer computing resources of varying capacities at different distances from end users. A Node (FN) closer to the network edge may have less powerful compared cloud, but processing computational tasks in FN limits long-distance transmission. How should be distributed between fog and cloud nodes? We formulate a universal non-convex Mixed-Integer Nonlinear Programming (MINLP) problem ...

In this letter, we study the uplink channel throughput performance of a proposed novel multiple-antenna hybrid-domain non-orthogonal multiple access (MA-HD-NOMA) scheme. This scheme combines conventional sparse code (SCMA) and power-domain NOMA (PD-NOMA) schemes in order to increase number users served as compared uses antennas at base station. To end, joint resource allocation problem for MA-H...

This paper proposes a novel network framework of intelligent reflecting surface (IRS)-assisted simultaneous wireless information and power transfer (SWIPT) non-orthogonal multiple access (NOMA) networks, where IRS is used to enhance the NOMA performance (WPT) efficiency SWIPT. We formulate problem minimizing base station (BS) transmit by jointly optimizing successive interference cancellation (...

In this paper, a novel concept called simultaneously transmitting and reflecting RIS (STAR-RIS) is introduced into the wireless-powered mobile edge computing (MEC) systems to improve efficiency of energy transfer task offloading. Compared with traditional reflecting-only RIS, STAR-RIS extends half-space coverage full-space by incident signals, also provides new degrees-of-freedom (DoFs) for man...

In this paper, we study a cognitive radio (CR)-enabled wireless powered communication network (WPCN) with an intelligent reflecting surface (IRS). A (CWPCN) consisting of one secondary network, in which hybrid access point broadcasts energy to multiple users on downlink and receives information signals uplink, shares the same spectrum existing primary network. consider underlay CWPCN is regulat...

Simultaneous transmission and reflection-reconfigurable intelligent surface (STAR-RIS) can provide expanded coverage compared with the conventional reflection-only RIS. This paper exploits energy efficient potential of STAR-RIS in a multiple-input multiple-output (MIMO) enabled non-orthogonal multiple access (NOMA) system. Specifically, we mainly focus on energy-efficient resource allocation MI...

In this paper, we study the optimal cooperative beamforming problem in amplify-and-forward (AF) multi-user and multi-relay networks, which face challenges of rapid node number variations per-node power limits. To achieve extra diversity gain, direct-link (source-to-destination) distributed relay-link signals are jointly exploited. The is formulated as maximum relay transmit minimization problem...

Phase retrieval aims at recovering unknown signals from magnitude measurements of linear mixtures. In this paper, we consider the phase with dictionary learning problem, which includes another prior information that signal admits a sparse representation over an dictionary. The task is to jointly estimate and magnitude-only measurements. To end, study two complementary formulations develop effic...
