Foreword by Guest Editors for the Special Issue on the 2016 Global Conference on Wireless and Optical Communications (GCWOC'16)
Wireless personal communications
Welcome to this special issue of Wireless Personal Communications. This special issue comprises a selection of best papers from the Global Conference on Wireless and Optical Communications (GCWOC'16). This 3-day event provided a platform for researchers from Europe, Asia and other parts of the world to exchange ideas, innovations and challenges encountered throughout the research process in these areas. This issue has been organized in two main blocks, placing papers related to wireless
... ations in the first block; the second block contains those papers whose scope is optical communications. Within each block, papers have been arranged taking into account the layer they are more related to, from bottom to top. A few of papers outside these scopes are included at the end. The GCWOC conference was held at the University of Malaga, Spain, during 5-7 September 2016, and was jointly organized by the University of Malaga (Spain), the Mehran University of Engineering and Technology (Pakistan), and the Sir Syed University of Engineering and Technology (Pakistan). The first paper is entitled "An Efficient Method for Investigating and Optimizing Near Field Characteristics of Planar Antenna Arrays". The author analyzes the near field of 2D planar antenna arrays with an analytical method, instead of using numerical methods, which are time consuming. The results show that the use of asymmetrical amplitude weighting coefficients, together with Chebyschev far-field technique, improves the side lobe suppression.
