Architectural Solutions Towards a 1,000 Channel Ultra- Wideband WDM Network
نویسنده
چکیده
In this paper architectural considerations for deployment of ultra-wideband (14501650 nm) WDM networks having a massive number of WDM channels (400-1,000), are presented. The fundamental networking building block is an all-optical ring comprised by ultra-wideband WDM Passive Optical Networks (PONs) interconnected via a suitable optical cross-connect. Each PON could aggregate traffic from hundreds of thousands of users. The resulting benefits in terms of node consolidation and enhancements of transported capacity for both residential and business users are analysed for a MAN/WAN network. The critical component for such a network is a single multiplexer/demultiplexer for the entire spectral range. This device is also presented and its performance in terms of coupling efficiency and crosstalk is calculated.

Outage Probability Bound and Diversity Gain for Ultra-Wideband Multiple-Access Relay Channels with Correlated Noises
In this paper, Ultra-wideband (UWB) multiple access relay channel with correlated noises at the relay and receiver is investigated. We obtain outer and inner bounds for the IEEE 802.15.3a UWB multiple access relay channel, and also, a diversity gain bound. Finally, we evaluate some results numerically and show that noise correlation coefficients play important role in determining relay position.

We consider the problem of low-complexity channel estimation in digital ultra-wideband receivers. We extend some of our recent sampling results for certain classes of parametric non-bandlimited signals and develop several methods that take advantage of transform techniques to estimate channel parameters from a low-dimensional subspace of a received signal, that is, by sampling the signal below ...

Ultra-wideband radio is an enabling microwave technology for broadband communication and high-resolution sensing. However, the full realization of its potential requires further research on ultra-wideband signal propagation and interference with existing narrowband systems. Such questions can be rigorously resolved from the fundamental viewpoint of electromagnetic theory. Yet, this approach has...
