A dynamic bandwidth allocation algorithm to enhance bandwidth efficiency for Ethernet PONs
SPIE Proceedings, 2006We discuss a phenomenon of upstream bandwidth waste in a conventional dynamic bandwidth allocation scheme and propose a novel upstream bandwidth allocation scheme to enhance upstream bandwidth efficiency in Ethernet PON, and evaluate performance of the proposed scheme in terms of upstream channel throughput, mean queueing delay, and mean queue length ...

An IIR adaptive line enhancer with controlled bandwidth
Proceedings of ICCS '94, 1997A previously proposed IIR adaptive line enhancer (ALE) is explored further. We propose a mechanism for controlling the bandwidth of the ALE in an adaptive manner. The proposed mechanism increases the bandwidth of the ALE whenever its peak is not close to a spectral line of the input signal to assure its fast convergence and decreases the bandwidth of ...

Algorithms and Reach Enhancement for Ultra High Bandwidth Transceivers
Optical Fiber Communication Conference, 2016The simultaneous reception of a DP-256QAM super-channel with an achievable information rate of 1.32Tb/s is demonstrated using a high bandwidth optical transceiver. An SNR improvement of 1dB is also demonstrated using MC-DBP after 2000km transmission.

Patch Antenna Bandwidth enhancement through the use of Metamaterials
2009 International Conference on Telecommunications, 2009This paper presents how Metamaterials can be used to enhance Antenna Bandwidth. To this purpose, a particular Metamaterial cell is introduced for which its design parameters are detailed. This cell is then used to enhance the performances of a microstrip antenna which can be found in communication systems.

Plasmon–Plasmon Hybridization and Bandwidth Enhancement in Nanostructured Graphene
Nano Letters, 2015Graphene plasmonic structures with long-range layering periodicity are presented. Resonance energy scaling with the number of graphene layers involved in plasmonic excitation allows these structures to support multiple plasmonic modes that couple and hybridize due to their physical proximity. Hybridized states exhibit bandwidth enhancements of 100-200%

Bandwidth enhancement in noncentered stacked patches
Microwave and Optical Technology Letters, 2001AbstractA complete study of the bandwidth extension of asymmetrical stacked patches as been carried out. A method that combines the effect of upper patch size and its displacement along the E‐plane axis has been analyzed. Results show new possibilities in the design of such antennas for the two studied cases: square and circular patches.

A CPW MEMS Switch with Enhanced Bandwidth
2007 Asia-Pacific Microwave Conference, 2007Shunt capacitive RF-MEMS switches over coplanar waveguides exhibit low isolation in the down-state position and high return loss in the up-state position at low frequencies. At high frequencies, they have a dual behavior with respect to these characteristics, which can significantly limit their operation bandwidth, as discussed in the literature.

Bandwidth and resolution enhancement through pulse compression
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2007A novel pulse compression technique is developed that improves the axial resolution of an ultrasonic imaging system and provides a boost in the echo signal-to-noise ratio (eSNR). The new technique, called the resolution enhancement compression (REC) technique, was validated with simulations and experimental measurements.
