Vehicular ad hoc networks (VANETs) have been identified as a key technology to enable intelligent transport systems (ITS), which are aimed to radically improve the safety, comfort, and greenness of the vehicles in the road. However, in order to fully

In this paper, an efficient method for transport tracking through a Wireless Dynamic Sensor Network (WDSN) is developed based on the measurement of the Received Signal Strength Indicator (RSSI) in a real urban environment. WDSN deployment is supporte

The use of multiple transmit and receive antennas is widely recognised as an effective technology to boost the capacity of wireless communication systems. Moreover, the combination of multiple-input multiple-output (MIMO) systems with multicarrier co

This work addresses the spectral e_ciency problem in LTE-Advanced systems that require multiple spectrum resources using a Round Robin scheduler that takes the channel quality information as an input. In order to asses the performance of this schedul

In the wireless communication systems, the objective of using array antennas is to extract the desired signal while filtering out the unwanted interferences. New methods are developed for the optimization and synthesis, in terms of the directivity an

In this paper, differential evolution (DE), one of the youngest paradigms in evolutionary computation, is applied to the process of synthesizing a planar array factor focused on sidelobe-level reduction. Sidelobe level is a critical array factor para

In this paper, a closed-loop pre-equalization approach for multiuser multicarrier code division multiple access (MC-CDMA) systems under a multiple-input multiple-output (MIMO) framework is presented. This work investigates the impact and limitations
