Design and Implementation of OFDM transmitter with Low Peak-to-Average Power Ratio

, 2007
High Peak-to-Average Power Ratio (PAPR) poses serious problem for the analog front end power amplifier design of Orthogonal Frequency Division Multiplexing (OFDM) systems. In this paper, an OFDM transmitter with PAPR reduction is proposed.

Use of data permutation to reduce the peak-to-average power ratio of an OFDM signal

, 2002
A set of fixed permutations is used in this paper to reduce the peak-to-average power ratio (PAR) of an orthogonal frequency division multiplexing (OFDM) signal. For this technique, K - 1 interleavers are used to produce K - 1 permuted sequences from the

Constellation Compaction Design to Reduce Both PAPR and Average Power in OFDM Systems

EURASIP Journal on Wireless Communications and Networking, 2010
This paper proposes a novel way to compact the constellation points in QAM modulation schemes and exploits this compaction to reduce the peak to average power ratio (PAPR) in orthogonal frequency division multiplexing (OFDM) systems.

Deep Learning Integration in PAPR Reduction in 5G Filter Bank Multicarrier Systems [PDF]

Iranian Journal of Electrical and Electronic Engineering
High peak-to-average power ratio (PAPR) has been a major drawback of Filter bank Multicarrier (FBMC) in the 5G system. This research aims to calculate the PAPR reduction associated with the FBMC system.

PAPR Reduction of Complex Wavelet Packet Modulation (CWPM) System using a Novel Hybrid Technique over Selective Rayleigh Fading Channel

Journal of Engineering and Sustainable Development, 2013
High Peak to Average Power Ratio (PAPR) of transmitted signal is one of the major drawbacks of the complex wavelet packet modulation (CWPM). Utilizing the advantage of concentrating the energy to certain subspaces of the discrete wavelet transform ...
