This paper proposes an experimental study of the architectures of the high power amplification stage and their influences on the system's linearity and power efficiency with application to wireless communication infrastructures. Two architectures are investigated: the single branch power amplification stage using class A/B power amplifiers and the promising(More)
This paper deals with digital base band signal processing algorithms, which are seen as enabling technologies for software-enabled radios, that are intended for the correction of the analog front end. In particular, this paper focuses on the design, optimization and testability of predistortion functions suitable for the linearization of narrowband and(More)
Vehicular Ad-hoc Network (VANET) has become an active area of research due to its major role to improve vehicle and road safety, traffic efficiency, and convenience as well as comfort to both drivers and passengers. This paper thus addresses some of the attributes and challenging issues related to Vehicular Ad-hoc Networks (VANETs). A lot of VANET research(More)
This paper suggests an automated validation approach in testing advanced digital signal processing algorithms. These algorithms, which are intended for the implementation of the base band processor of Software defined radios, are developed in software (Digital Signal Processors DSP) and hardware (FPGA) environments in order to meet real-time and offline(More)
This paper proposes a system level study of an adaptive communication gateway for Intelligent Vehicles (IV) in Intelligent Transportation System (ITS). This study starts with the analysis of the different communications standards that are expected to link the IV to mobile devices inside the vehicle, other IVs in the ITS network, the road side unites and the(More)
