PAPR Reduction of Multicarrier Faster-Than-Nyquist Signals With Partial Transmit Sequence

open access: yesIEEE Access, 2017
Multicarrier faster-than-Nyquist (MFTN) signaling is a spectral efficient transmission scheme for future communication systems. Similar as general multicarrier signals, the high peak-to-average power ratio (PAPR) is also one of the main drawbacks of MFTN

Peak-to-Average Power Ratio of Multicarrier Faster-Than-Nyquist Signals: Distribution, Optimization and Reduction

open access: yesIEEE Access, 2018
Multicarrier faster-than-Nyquist (MFTN) is a spectral efficient transmission scheme for future communication systems. However, as one of the most important drawbacks of multicarrier transmission systems, the peak-to-average power ratio (PAPR) of MFTN ...

Packet Format Design and Decision Directed Tracking Methods for Filter Bank Multicarrier Systems

open access: yesEURASIP Journal on Advances in Signal Processing, 2010
Packetized data transmission is commonly used in wireless communication systems. Each packet starts with a preamble which is used to synchronize the receiver with carrier frequency of the incoming signal, to find a good timing phase, and to identify the ...

An adaptive hidden Markov model for indoor OFDM based wireless systems

open access: yesJournal of Telecommunications and Information Technology, 2004
Detailed physical layer simulation of orthogonal frequency division multiplexing (OFDM) systems requires programs that execute too slowly due to long coherence time of the indoor mobile channel.

Multicarrier Access and Routing for Wireless Networking

open access: yesEURASIP 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.

Computationally Efficient Power Allocation Algorithm in Multicarrier-Based Cognitive Radio Networks: OFDM and FBMC Systems

open access: yesEURASIP 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

open access: yesEURASIP 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).
