Resource Allocation with Interference Avoidance in OFDMA Femtocell Networks
TL;DR: This paper investigates a self-organization strategy for physical resource block (PRB) allocation with QoS constraints to avoid the co-channel and co-tiered interference and develops a greedy algorithm to solve the resource allocation formulation.
Journal ArticleDOI
Enabling Low-Latency Applications in Fog-Radio Access Networks
TL;DR: Examples and numerical results show that ultra low-latency services can be achieved by the F-RAN by properly handling the tradeoff, and the need for a service framework for F- RAN to cope with the complex tradeoff among performance, computing cost, and communication cost is discussed.
Journal ArticleDOI
Compressed Sensing Detector Design for Space Shift Keying in MIMO Systems

TL;DR: This work proposes a compressed sensing based detector, NCS, by formulating the SSK-type detection criterion as a convex optimization problem, which requires only O(ntNrNt) complexity, outperforming the O(NRNtnt) complexity in the ML detector, at the cost of slight fidelity degradation.
Journal ArticleDOI
Generalized Precoder Design Formulation and Iterative Algorithm for Spatial Modulation in MIMO Systems With CSIT
TL;DR: Simulation results show that the proposed designs improve the performance of SM-/GSM-MIMO systems and outperform existing precoding methods with a potentially higher complexity cost.
Proceedings ArticleDOI
Latency-Driven Cooperative Task Computing in Multi-user Fog-Radio Access Networks
TL;DR: A latency-driven cooperative task computing algorithm with one-for-all concept for simultaneous selection of the F-RAN nodes to serve with proper heterogeneous resource allocation for multi-user services is proposed.
