Smart cities take advantage of recent Information and Communication Technology (ICT) developments to provide added value to existing public services and improve quality of life for the citizens. The Internet of Things (IoT) paradigm makes the Internet more pervasive where objects equipped with computing, storage, and sensing capabilities are interconnected with communication technologies. Because...
The Internet of Things (IoT) paradigm makes the Internet more pervasive. IoT devices are objects equipped with computing, storage and sensing capabilities and they are interconnected with communication technologies. Smart cities exploit the most advanced information technologies to improve public services. For being effective, smart cities require a massive amount of data, typically gathered from...
Orthogonal Frequency Division Multiplexing (OFDM) systems generally require estimation and tracking of the channel parameters to perform coherent demodulation. A pilot pattern for channel estimation in OFDM systems mostly consists of equidistant pilot symbols in time and frequency direction. The channel estimation can be done by exploiting the correlations of the channel frequency response at different...
The Automatic Identification System is a universal shipborne system adopted to improve safety at sea and efficiency of navigation. This system allows to identify and localize vessels in a short range for collision avoidance by exchanging messages with navigational information.
AIS is a universal shipborne Automatic Identification System recently introduced for traffic monitoring and safety at sea. Ships exchange navigational information to identify and localize vessels in a short range to avoid collisions. AIS signals use Gaussian Minimum Shift Keying (GMSK) for transmission. There is a growing need to develop a system which provides global maritime surveillance in order...
This contribution is attempting to show how a route diversity can improve the traffic behavior of a connection between two network entities. The most used transmission protocols TCP and UDP control the quasi-totality of the Internet traffic. However they are not capable to carry out all the traffic generated by the Internet as they lead to congestion and packet loss out of the quality of service required...
The technique presented here improves a previously proposed [1] Iterative Channel Data Estimation (ICDE) technique in M-ary data transmission over time-variant frequency selective channels by using a proportionate sample adaptive filter for channel tracking on a Per-Survivor Processing (PSP) basis. Henceforth, we call the approach using proportionate algorithm P-ICDE. The data detector is a simple...
