Optical beam forming for phased-array antennas

The activities of the Telecommunication Engineering (TE) group span the communications spectrum from copper cables, optical fibres, microwaves, radio and electromagnetic compatibility. Our research concentrates on optical signal processing and networks, mobile communications, microwave techniques and radiation from ICs and PCBs [1]. A considerable (and particularly interesting) part of it is related to optical beam forming for phased array antennas, using optical ring resonators.\ud In this article the theoretical basics and practical challenges of this interesting research topic will be summarized.\u

A concept for modern virtual telecommunication engineering office

High-performance modern Internet allows internal delivery and complement of attractive (mobile) services in the same way and QoS that are in the LANs. The world economics is widely characterized nowadays via the stable trends that the large and mid-range companies and authorities let in ever greater extent to outsource own engineering services via external smaller service providers. A concept for a modern virtual telecommunication engineering office under use of Service-Oriented Architectures and Cloud Computing technologies has been offered. Multiple use cases for virtual telecommunication engineering office have been discussed. As a significant example, the CANDY Framework and Online Platform have been examined. The important development trends for the CAD for network planning regarding to the tool integration and effective access optimization have been discussed. The CANDY system has been represented as an exhibit at CeBIT 2007,2008, 2011 in Hannover

Bringing Optical Communications to the General Public: an Innovative Bachelor Thesis

The United Nations “International year of light 2015” strives to highlight the importance of optical technologies in our everyday lives. Fibre optic communication is one such technology: the growth of internet and its associated services are enabled by the vast transmission bandwidth provided by optical networks. However, the general public is not well aware of the optical and electronic fundamentals of the underlying transmission systems. Here we present the development of a bachelor thesis in Telecommunication Engineering in which a small-scale fibre-optic link is built and the electronics required to transmit music over this link are implemented. The resulting system demonstrates, in a very intuitive way, how information is transmitted over an optical fibre.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech

Mixed integration of CDIO skills into telecommunication engineering curricula

Spain has been intensively involved in designing engineering curricula for the last two years and next academic year all engineering schools will be deploying all bachelor programs adapted to the EHEA and to the Spanish laws. The different frameworks that set the conditions of the process of drawing up new curricula emphasize the use of competency-based learning and the insertion of certain generic skills within the structure of the new plans. In the school of Telecommunication Engineering of Barcelona, the CDIO initiative (Conceive-Design-Implement-Operate) first developed jointly by MIT and some Swedish Universities, has been chosen as paradigm for new engineering curricula design. We used a mixed approximation to integrate CDIO skills into the study plans. In this paper we will explain the approach to include generic skills when designing new curricula.Peer ReviewedPostprint (published version

Digital video technology in the English for telecommunication engineering classroom

Uno de nuestros retos como profesores de Inglés para Fines Específicos es ser capaces de involucrar a los estudiantes de postgrado en la utilización del inglés como una herramienta para compartir sus proyectos e interactuar, en nuestro caso con otros ingenieros, sin perder de vista el uso de la lengua extranjera para la vida cotidiana. Si motivación y autenticidad son dos palabras claves en la enseñanza de IFE, internet y sus muchas posibilidades se presenta como una fuente muy valiosa a la hora de encontrar materiales auténticos, atractivos y motivadores que emplear en el aula de IFE. El objetivo de este artículo es compartir una experiencia práctica en el uso de las tecnologías de vídeo digital para enseñar Inglés para Ingenieros de Telecomunicación, llevada a cabo con alumnos de postgrado de la Universidad de Las Palmas de Gran Canaria durante los cursos 2012-13 y 2013-14. Este curso fue diseñado en respuesta a las necesidades comunicativas de los estudiantes dentro de su propia especialidad, teniendo en cuenta las carencias particulares de cada estudiante, sin descuidar la enseñanza de la gramática y el léxico entre otras herramientas lingüísticas. Para ello, realizamos un estudio previo de las necesidades de estos alumnos. En este artículo, explicaremos las razones que nos llevaron a crear nuestros propios materiales, el proceso de selección y los resultados obtenidos.One of our challenges as teachers of English for Specific Purposes is to be able to involve post-graduate students in the use of English as a tool to share their projects and interact in our case with other engineers, without losing sight of the use of foreign language for everyday life. If motivation and authenticity are two key words in teaching ESP, internet and its many possibilities is presented as a valuable source to finding authentic, engaging and motivating materials to be used in the ESP classroom. The aim of this article is to share a practical experience in the use of digital video technology to teach English for Telecommunications Engineers, conducted with post-graduate students from the University of Las Palmas de Gran Canaria during the 2012-13 and 2013-14 school years. This course was designed in response to the students’ communicative needs within their own specialty, taking into account the particular requirements of each student, without neglecting the teaching of grammar and vocabulary and other language tools. We carried out a preliminary study of the needs of these students. In this article, we will explain the reasons that led us to create our own materials, the selection process and results

A Fair and Efficient Packet Scheduling Scheme for IEEE 802.16 Broadband Wireless Access Systems

This paper proposes a fair and efficient QoS scheduling scheme for IEEE 802.16 BWA systems that satisfies both throughput and delay guarantee to various real and non-real time applications. The proposed QoS scheduling scheme is compared with an existing QoS scheduling scheme proposed in literature in recent past. Simulation results show that the proposed scheduling scheme can provide a tight QoS guarantee in terms of delay, delay violation rate and throughput for all types of traffic as defined in the WiMAX standard, thereby maintaining the fairness and helps to eliminate starvation of lower priority class services. Bandwidth utilization of the system and fairness index of the resources are also encountered to validate the QoS provided by our proposed scheduling scheme
