Energy consumption of customer premises equipment (CPE) has become a serious issue in the new generations of time-division multiplexing passive optical networks, which operate at 10 Gb/s or higher. It is becoming a major factor in global network energy consumption, and it poses problems during emergencies when CPE is battery-operated. In this paper, a(More)
This paper presents a new long reach PON (LR-PON) scenario operating at a single carrier of 40-Gbit/s for downstream, as an upgrade option of the LR-PON evolutionary strategy. An electrical 3-level duobinary modulation format was proposed for the 40-Gbit/s downstream transmission. In this paper the required optical signal to noise ratio (OSNR) and optical(More)
Wireless networks have recently evolved to very complex systems, due to the increasing diversity of competing radio technologies, applications and service providers which coexist in the same environments. In such a scenario, we argue that performance optimization cannot only rely on advanced hardware platforms and radio capabilities, but mainly depends on(More)
The future 5G wireless infrastructure will support any-to-any connectivity between densely deployed smart objects that form the emerging paradigm known as the Internet of Everything (IoE). Compared to traditional wireless networks that enable communication between devices using a single technology, 5G networks will need to support seamless connectivity(More)
Software-Defined Radio (SDR) technology is evolving rapidly, offering higher flexibility for wireless communication networks. For the sake of performance, and power consumption, filtering is commonly implemented in hardware using FPGAs. Pulse shaping in the transmitter and the corresponding matched filtering in the receiver, which together satisfy the(More)
Quarter-pel (q-pel) motion compensation (MC) is one of the features of H.264/AVC that aids in attaining a much better compression factor than what was possible in preceding standards. The better performance however also brings higher requirements for computational complexity and memory access. This article describes a novel data storage and the associated(More)
This letter proposes a fast parallel and deeply pipelined architecture for realtime H.264 intra 4×4 prediction capable of handling up to 32 High Definition video streams (1920× 1080 @ 30 fps) simultaneously, while offering high flexibility and consuming only a fraction of resources available on modern FPGA’s. The design has been validated on target using a(More)
