Performance monitoring is one of the key features to create self-managed optical networks. Monitoring the characteristics of an optical channel is important for designing robust and reliable optical telecommunication system. This thesis examined the use of ...
A single failure in a communication network may trigger many alarms. When the communication network uses optical fibres as a transmission medium and increases its capacity by using Wavelength Division Multiplexing (WDM) and Space Division Multiplexing (SDM ...
As dictated by ongoing technology scaling and the advent of multi-core systems, each new generation of microprocessors and digital signal processors provides higher computing power and data throughput. However, the available bandwidth of the input/output ( ...
In wireless portable applications, a large part of the signal processing is performed in the digital domain. Digital circuits show many advantages. The power consumption and fabrication costs are low even for high levels of complexity. A well established a ...
The failure of a single optical link or node in a Wavelength Division Multiplexing (WDM) network may cause the simultaneous failure of several optical channels. In some cases, this simultaneity may make it impossible for the higher level (SONET or IP) to r ...
In this paper, we study a coherent optical MIMO (COMIEMO) multi-mode fiber link proposed for enhancing the fiber information capacity. We examine the statistical characterization of the equivalent MIMO channel and the improvement in the fiber capacity due ...
A new optical local area network that combines dense Wavelength Division Multiplexing (WDM) techniques and coherent transmission benefits is presented. A new multichannel protocol is specified based on Ethernet, using WDM to carry multiple channels on a si ...
A single failure in a communication network may trigger many alarms. When the communication network uses optical fibres as transmission medium and increases its capacity by using Wavelength Division Multiplexing (WDM), the number of alarms and the difficul ...
In this paper we present current mode, programmable, binary tree MIN/MAX filters designed for nonlinear data processing. Proposed circuits can be used in image filtration, to realize operations such as erosion or dilatation that are useful in noise reducti ...
Ultra low power circuits are in high demand in many applications especially in wireless sensor networks (WSN), where energy is scavenged from environment. WSN systems contain different blocks, such as: sensors, filters, analog-to-digital converters, very o ...
