  journal={Wireless Personal Communications},
In multicarrier transmission schemes, the essential requirement on the elementary pulse or envelope function is the orthogonality with its time-frequency shifted versions. However, the time and frequency dispersion of the mobile radio channel leads to the loss of orthogonality which produces intersymbol interference (ISI) and interchannel interference (ICI). Therefore, another requirement on the elementary pulse has to be imposed: the good localization in time and frequency. Based on the… 
Multi-pulse/single-pulse design for maximizing SIR in partially equalized OFDM systems over highly dispersive channels
This paper considers a mobile transmission by the OFDM/BFDM technique that combines single pulse modulation or multi pulse modulation combined with a partial equalization of few neighboring pulses at the receiver to optimize the overall system performance.
An evolutionary time-frequency approach to multi-carrier wireless communications
A time-frequency approach to modeling and estimating the communication channel, and to symbol transmission in multi-carrier wireless systems, based on the evolutionary spectral theory of signals and systems is provided.
Iterative detection for multicarrier transmission employing time-frequency concentrated pulses
A symbol detector is derived which first calculates a sufficient statistic for the unknown data symbols from the linearly combined output signals of a filter bank, and second, performs an iterative maximization of the likelihood function.
Optimal OFDM Design for Time
Transmission over wireless channels is subject to time dispersion due to multipath propagation as well as frequency dis- persion due to the Doppler effect. Standard orthogonal frequency- division

This work presents a general framework for pulse shape design and shows how to design lattice-OFDM systems (lattice and pulse shape) optimally for time and frequency-dispersive channels in order to minimize the joint ISI/ICI.
Nonorthogonal pulseshapes for multicarrier communications in doubly dispersive channels
This work derives the expected intersymbol/interchannel interference of such a nonorthogonal FDM (NOFDM) system under the assumption of a wide-sense stationary uncorrelated scattering (WSSUS) channel and compares OFDM and NOFDM schemes with regard to robustness against delay/Doppler spread.
Optimum Pulse Shaping for OFDM/BFDM Systems Operating in Time Varying Multi-Path Channels
Numerical results show that optimized BFDM systems can outperform conventional OFDM systems with respect to SIR, and biorthogonality offers more freedom to design pulses improving robustness of the multi-carrier system against channel dispersion.
Optimized pulse shaping for OFDM multi-user communications over doubly dispersive channels
A pulse-shaped OFDM based analysis of inter-symbol/inter-carrier interference for synchronous downlink and asynchronous uplink of multi-user systems and an optimization procedure for designing pulses maximizing the SIR is proposed.
On the time-frequency localisation of 5G candidate waveforms
A measure of time-frequency localisation (TFL) for sets of orthogonal waveforms, based on Heisenberg's well-known Uncertainty Principle, allowing for the containment of OFDM and FBMC multicarrier signals over the entire bandwidth to be determined.
A New Approach to Multicarrier Pulse Design for Doubly-Dispersive Channels
Two low-complexity iterative equalization algorithms are proposed which leverage the resulting ISI/ICI structure, one based on soft feedback and the other on hard feedback, and indicate that the soft feedback algorithm achieves estimation performance close to the matched filter bound in most scenarios.
