Millimeter Waves (mmWave) have recently attracted a lot of research interest in different domains. Among others, localization using mmWave became one of its major applications. In this paper, the tactile localization concept aiming at reaching sub-cm accuracy is introduced. The main challenges and approaches to realize tactile localization are also presented. The paper will mainly focus on the need...
In fluctuating mobile environments where operators have to confront the increasing demands of their subscribers, insufficient spectrum poses capacity limitations. This work studies the gain that cooperative multicast transmission provides when used to boost the data rate in Device-to-Device (D2D) communication, enabling data sharing among users. A multicast network combines the benefits of both a...
This paper presents our approach integrating a high level of intelligence within telecommunication networks. Artificial intelligence has proved its efficiency in resolving complex issues in different fields like air traffic control, robotics, and medical diagnosis. However its usage in telecommunication networks is still very moderated. The main objectives of our framework is to encourage the deployment...
This work adopts the paradigm of cloud computing over the framework of Device-to-Device (D2D) communications in LTE-Advanced to enable mobile devices to offer network services to nearby devices, thus acting as mobile cloudlets, and to offload cellular traffic from the core network. Hence, any mobile device seeking a new service can search and discover for nearby services with the help of the LTE-A...
In this paper, a design of a compact multi-band antenna with reconfigurability is presented. The design is based on incorporating two split-ring resonators to an F-shaped monopole antenna. Electronic switches are mounted across these resonators to serve in activating or deactivating their resonance frequency, thus leading to reconfigurability. The antenna is microstrip line-fed, and is on a 40 mm...
The hardware simulator facilitates the test and validation cycles by replicating channel artifacts in a controllable and repeatable laboratory environment. After a description of the MIMO channel models and the hardware simulator architecture, this paper presents new implementation algorithm of its digital block. The proposed algorithm allows the selection of specific environments and various scenarios,...
Advanced antenna arrays at the base stations are one of the key techniques to improve the downlink capacity of WCDMA cellular systems. Traditionally, linear and circular arrays are used to form the beams. In this paper, cylindrical antenna arrays with various types of input excitations are proposed, and the beam steering adaptive antenna technique is considered. The user capacity per cell among the...
