Price-Based Resource Allocation in Massive MIMO H-CRANs with Limited Fronthaul Capacity

  • Gacanin H.
  • Osamu Muta
  • Wanming Hao

In this paper, we study the frequency and power allocation problem in remote radio head cluster (RRHC)-based millimeter wave (mmWave) massive MIMO heterogeneous cloud radio access networks (H-CRANs) with limited fronthaul capacity. The coordinated multipoint (CoMP) transmission is applied in each RRHC for cancelling the intra-cluster interference. To avoid the ...

Recent Developments in Modal Analysis of Elliptical Waveguides

  • Agrawal G.
  • Antikainen. A
  • Essiambre R.

We present an overview on a recently developed novel mathematical method to determine the transverse modes of elliptical waveguides. The method is based on a perturbation expansion and avoids the numerical issues of the traditional Mathieu function treatment without compromising generality or versatility.

Earables for Personal- scale Behaviour Analytics

  • Kawsar F.
  • Mathur A.
  • Min C.
  • Montanari A.

We present eSense - an open and multi-sensory in-ear wearable platform to detect and monitor human activities. eSense is a true wireless stereo (TWS) earbud with dual-mode Bluetooth and Bluetooth Low Energy and augmented with a 6-axis inertial measurement unit and a microphone. We discuss the eSense platform and its ...

Long Distance and High Bandwidth Wireless Link Tests For a 39 GHz to 28 GHz 5G Low-Cost Repeater

  • Maier S.
  • Schlesinger H.
  • Templ W.
  • Viswanathan H.

This paper presents a low-cost millimeter-wave repeater for range extension in a 5G fixed wireless access system. It simply converts the wireless fronthaul signals in the 39 GHz band to the wireless access signals in the 28 GHz band without any base-band signal processing. Initial outdoor over-the-air tests with a ...

1.6 Tbps Virtual-Carrier Assisted WDM Direct Detection Transmission over 1200 km

  • Buchali F.
  • Buelow H.
  • Schuh K.
  • Thai Le S.

Single-sideband (SSB) self-coherent detection (SCD) has attracted a lot of attention recently as a promising technology for short and medium reach optical transmission systems, such as data center interconnect (DCI) and metro applications, due to the low cost, the compact module size and the possibility of electrical dispersion compensation (EDC). ...

Optimal Control of Distributed Computing Networks with Mixed-Cast Traffic Flows

  • Llorca J.
  • Modiano E.
  • Sinha A.
  • Tulino A.
  • Zhang J.

Distributed computing networks, tasked with both packet transmission and processing, require the joint optimization of communication and computation resources. We develop a dynamic control policy that determines both routes and processing locations for packets upon their arrival at a distributed computing network. The proposed policy, referred to as Universal Computing ...

Statistical Analysis of Downlink Transmissions for Ultra-Reliable Low-Latency Communications

  • Shariatmadari H.
  • Uusitalo M.

The fifth generation (5G) of wireless systems aims at providing connectivity for a large number of applications by introducing new services. Ultra-reliable low-latency communications (URLLC) is one of the considered services that envisions mission-critical applications, such as industrial Internet, remote surgery, and intelligent vehicular systems. The 5G new radio (NR) ...

The increasing demand for highly customized products, as well as flexible production lines, can be seen as trigger for the "fourth industrial revolution", referred as "Industrie 4.0". Current systems are usually using wire-line technologies to connect sensors and actuators. To enable a higher flexibility such as moving robots or drones, ...

Predictive Autoscaling Orchestration for Cloud-native Telecom Microservices

Mobile traffic is dramatically increasing in recent several years with the evolution of mobile network toward 5G era. Leveraging network function virtualization (NFV) and cloud computing the elasticity is the advantage of mobile network systems. The autoscaling orchestrator can adjust the number of virtual network functions (VNFs) in a telecom ...

The Capacity Effects of Relays in Residential 5G Networks

  • Andrews M.
  • Viswanathan H.

We examine the effects of introducing relays into millimeter-wave residential access networks. Single-hop networks require professional customer equipment installation on rooftops in order to obtain the necessary line-of-sight properties. An alternative is a two-hop approach with relays that each serve multiple homes. In this the final access links do not ...

Rank Minimization for Snapshot Compressive Imaging

Snapshot compressive imaging (SCI) refers to compressive imaging systems where multiple frames are mapped into a single measurement, with video compressive imaging and hyperspectral compressive imaging as two representative applications. Though exciting results of high-speed videos and hyperspectral images have been demonstrated, the poor reconstruction quality precludes SCI from wide ...

Managing Quality of Service Through Intelligent Scheduling in Heterogeneous Wireless Communications Networks

Small Cells are being deployed alongside pre-existing Macro Cells in order to satisfy demand during the current era of exponential growth in mobile traffic. Heterogeneous networks are economical because both cell tiers share the same scarce and expensive spectrum. However, customers at cell edges experience severe cross-tier interference in channel ...

Pervasive Communities in the Internet of People

The Internet has traditionally been a device-oriented architecture where devices with IP addresses are first-class citizens, able to serve and consume content or services, and their owners take part in the interaction only through those devices. The Internet of People (IoP) is a recent paradigm where devices become proxies of ...

Subcarrier and Power Allocation for the Downlink of Multicarrier NOMA Systems

This paper investigates the joint subcarrier and power allocation problem for the downlink of a multi-carrier non-orthogonal multiple access (MC-NOMA) system. A novel three-step resource allocation framework is designed to deal with the sum rate maximization problem. In Step 1, we relax the problem by assuming each of the users ...
