How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Article
Full-text available
Satellite networks are expected to perform a vital role in future communication systems, with complex features and seamless integration with ground-based infrastructure. This paper presents a novel simulation framework capable of providing a detailed assessment of a satellite communication’s network performance in realistic scenarios. The proposed...
Article
A Vehicular Ad-hoc Network (VANET) enables vehicles to communicate with each other directly or via roadside infrastructure in order to improve road safety and efficiency. Within a VANET, communications can potentially alter vehicular mobility, and conversely that mobility could potentially influence vehicular communications. Therefore, a VANET simu...

The use of TV white spaces as an alternative to overcome spectrum scarcity is a huge opportunity for new telecommunication systems and services. While being attractive for its desirable propagation characteristics, this part of the spectrum imposes a major difficulty from design and regulatory perspectives: how to optimize the use of spectrum and t...
Article
The explosive growth of mobile communications, and the overly crowded and expensive spectrum have pushed both system engineers and operators to make their systems as spectrally efficient as possible in order to accommodate the increasing traffic demand. This article is a tutorial introduction to the orthogonal subchannel (OSC) technique. OSC was ad...
Conference Paper
Location Based Services can generate variety of new commercial applications and create new streams of revenue. However, there is currently no simple indoor positioning method for low-end devices which have no Wi-Fi or GPS capability. This paper presents a novel and simple audio-based localization system to provide location-aware content for low-end...
Conference Paper
In order to have the White Spaces of the UHF broadcast band (470–790 MHz) in use by unlicensed users, new implementation challenges and special efforts still need to be done. Regulators can significantly impact the feasibility of implementation through requirements on sensing thresholds or by defining emission limits of unlicensed users. This paper...

Conference Paper
Speech quality is an important measurement for performance evaluation in a wireless mobile communication system since voice is still the most used service on it. The speech quality evaluation in GSM system employing narrowband and wideband AMR codecs with Orthogonal Sub Channel (OSC) technique is addressed in this paper. OSC is a feature proposed i...
Conference Paper
Full-text available
Re-farming of 900 MHz band into HSPA has been started and is likely to happen later with LTE. Typically operators have less than 10 MHz block of 900 MHz spectrum and therefore co-existence of two systems in that band is causing challenges. One of the major issues is the high GSM voice traffic that will remain in the GSM network. How to cope the sam...
