Full-duplex bidirectional transmission at 10 Gb/s is demonstrated for extended wavelength division multiplexed passive optical network (WDM-PON) applications, achieving transmission distances up to 25 km of standard single mode fiber (SSMF) when using a low-bandwidth (approximately 1.2 GHz) reflective semiconductor optical amplifier (RSOA) for signal(More)
The advanced complexity and heterogeneity of modern telecommunication systems mostly lead to the incorporation of heterogeneous implementation technologies and design styles. Consequently, the design representation of such systems often requires the mixed use of distinct model of computations at different abstraction layers. Therefore, heterogeneous(More)
Hardware±software co-design is the cornerstone in the design of complex systems that involve both hardware and software. This paper presents a co-design approach where the co-simulation between hardware and software takes place early enough in the design cycle. The proposed platform is based on the extension of existing instruction set processor simulators(More)
The design and joint simulation of rhe heterogeneous parts of a system in a unified environment offers many ahantages including reduced system design and debug times as well as increased simulation accuracy. In this paper it will be presented a couple of flexible interfaces that have been implemented for bridging VHDL with Electromechanical Systems(More)
An Analogue to Digital Converter (ADC) implemented in CMOS technology (90nm TSMC) is described in this paper which is based on a binary tree structure and has a configurable 4, 8 or 12-bits resolution. The function performed at the nodes of the binary tree is an integer division by a proper power of 2, that is implemented by a novel circuit. The developed(More)
A system capable of estimating the position of a mobile target based on the error rate of the received infrared patterns has been presented recently in [1]. In the present work, we explore the effect of using different infrared patterns to the estimation accuracy, the instant noise immunity and the system speed. We apply interleaving and forward error(More)
