A goal programming methodology for multiobjective optimization of distributed energy hubs operation [PDF]
, 2014 This paper addresses the problem of optimal energy flow management in multicarrier energy networks in the presence of interconnected energy hubs. The overall problem is here formalized by a nonlinear constrained multiobjective optimization problem and ...

Conjugate root offset-QAM for orthogonal multicarrier transmission [PDF]
EURASIP Journal on Advances in Signal Processing, 2016 Current implementations of OFDM/OQAM are restricted to band-limited symmetric filters. To circumvent this, non-symmetric conjugate root (CR) filters are proposed for OQAM modulation. The system is applied to Generalized Frequency Division Multiplexing (GFDM) and a method for achieving transmit diversity with OQAM modulation is presented.

Power spectrum characterization of systematic coded UW-OFDM systems [PDF]
, 2013 Unique word (UW)-OFDM is a newly proposed multicarrier technique that has shown to outperform cyclic prefix (CP)-OFDM in fading channels. Until now, the spectrum of UW-OFDM is not thoroughly investigated. In this paper, we derive an analytical expression

Multicarrier Access and Routing for Wireless Networking
EURASIP Journal on Wireless Communications and Networking, 2005 A multicarrier access and routing system has been proposed for use in wireless networks. Users within each cell access a radio port (RP). All RPs are connected to a radio exchange node (REN) which routes the calls or packets.

EURASIP Journal on Advances in Signal Processing, 2010 Cognitive Radio (CR) systems have been proposed to increase the spectrum utilization by opportunistically access the unused spectrum. Multicarrier communication systems are promising candidates for CR systems. Due to its high spectral efficiency, filter

FTN multicarrier transmission based on tight Gabor frames
EURASIP Journal on Wireless Communications and Networking, 2017 A multicarrier signal can be synthesized thanks to a symbol sequence and a Gabor family (i.e., a regularly time–frequency shifted version of a generator pulse).
