WIRELESSHD VIDEO TRANSMISSION OVER MULTICARRIER ERROR-CORRECTIONCHANNELS [PDF]
Journal of Computer Science, 2012 Uncompressed High-Definition video streaming over extremely high frequency using wireless technologies , also known as WirelessHD, is a challenge problem because of the high data rate requirement and channel variations. The advantages in RF technology and the huge bandwidth available in the 57-66 GHZ millimeter wave open new era for High Definition ...

Numerical Approaches in Nonlinear Fourier Transform‐Based Signal Processing for Telecommunications
Studies in Applied Mathematics, Volume 154, Issue 1, January 2025.ABSTRACT We discuss applications of the inverse scattering transform, also known as the nonlinear Fourier transform (NFT) in telecommunications, both for nonlinear optical fiber communication channel equalization and time‐domain signal processing techniques.

Pulse Shaping, Localization and the Approximate Eigenstructure of LTV Channels
, 2008 In this article we show the relation between the theory of pulse shaping for WSSUS channels and the notion of approximate eigenstructure for time-varying channels. We consider pulse shaping for a general signaling scheme, called Weyl-Heisenberg signaling,

International Journal of Energy Research, Volume 2025, Issue 1, 2025.The growing frequency of extreme natural and human‐induced events underscores the critical need to enhance the resilience of power systems. Multimicro grids (MMGs), integrating distributed energy resources (DERs), such as renewable generation and energy storage systems (ESSs), offer a promising solution by enabling power exchange both among ...

Sum-rate maximisation comparison using incremental approaches with different constraints [PDF]
, 2009 In this work, the problem of rate maximisation of multichannel systems is considered. Two greedy allocation approaches using power (GPA) and bit (GBA) loading schemes with a slight difference in design constraints that aiming to maximise the overall ...

International Journal of Energy Research, Volume 2025, Issue 1, 2025.This paper presents an innovative 24‐h scenario–based microgrid energy management system (MG‐EMS) designed to achieve cost reduction and emission reduction under conditions of uncertainty. Furthermore, a multiobjective hybrid heuristic algorithm, named hybrid multiobjective particle swarm optimization and lightning search algorithm (hMOPSO‐LSA), is ...

A Hybrid Single-Carrier/Multicarrier Transmission Scheme with Power Allocation
EURASIP Journal on Wireless Communications and Networking, 2007 We propose a flexible transmission scheme which easily allows to switch between cyclic-prefixed single-carrier (CP-SC) and cyclic-prefixed multicarrier (CP-MC) transmissions. This scheme takes advantage of the best characteristic of each scheme, namely,

Multicarrier transmission in a mobile radio channel
Electronics Letters, 1996 A multicarrier modulation system designed for communication in a multipath, mobile radio channel is described. The effect of introducing channel coding is investigated and the improvement in BER performance is shown. A comparison is made between the modulation schemes of DPSK and DQPSK.

CDMA Transmission with Complex OFDM/OQAM
EURASIP Journal on Wireless Communications and Networking, 2007 We propose an alternative to the well-known multicarrier code-division multiple access (MC-CDMA) technique for downlink transmission by replacing the conventional cyclic-prefix orthogonal frequency division multiplexing (OFDM) modulation by an advanced ...
