PERFORMANCE EVALUATION OF HYBRID PTS-SLM TECHNIQUES VERSUS CONVENTIONAL PTS

International Journal of Intelligent Computing and Information Sciences, 2014
Orthogonal Frequency Division Multiplexing (OFDM) is an attractive technique for wirelesscommunication over frequency-selective fading channels. Suffer from high Peak-to-Average PowerRatio (PAPR) limiting OFDM usage and reduces the efficiency of High ...

Efficient reduction of peak-to-average power ratio in multiple-input multiple-output orthogonal frequency-division multiplexing system by shuffling cluster sequences

ETRI Journal
We propose a shuffling cluster sequence technique without separate side infor-mation (SI) for multiple-input multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) systems.

Determinants of performance when the Counter Movement Jump performs in acute fatigue

Revista Brasileira de Cineantropometria e Desempenho Humano, 2014
This work analysed the changes that occur in kinetic-temporal parameters and the electromyographic activity of lower limb muscles during the performance of maximum Counter Movement Jumps (CMJ) done with and without muscular fatigue, to explain the ...

Supervised RNN-PTS framework for PAPR reduction and performance optimization in optical OTSM-VLC systems

Results in Optics
This paper presents a supervised recurrent neural network–based partial transmit sequence (S–RNN–PTS) approach for reducing – the – peak-to-average power ratio (PAPR) in optical orthogonal time–sequence multiplexing (OTSM) visible-light communication ...

Whale optimization‐based PTS scheme for PAPR reduction in UFMC systems

IET Communications
This paper proposes a whale optimization algorithm (WOA)‐based partial transmit sequence (PTS) scheme called WOA‐PTS to reduce the high peak‐to‐average power ratio (PAPR) for universal filtered multi‐carrier (UFMC) systems.

Reducing peak-to-average power ratio of filtered non-orthogonal multiple access and new radio 5g waveforms using hybrid partial transmit sequence-companding technique

ETRI Journal
For fifth-generation (5G) and beyond 5G communications, filtered nonortho-gonal multiple access (F-NOMA) can be used as a waveform contender. Filtering-based waveform frameworks provide suppression of out-of-band emission (OOBE) and asynchronous ...

Enhanced Sub-Block Partitioning and Effective Post-Processing for the PTS Algorithm

Tikrit Journal of Engineering Sciences
The transmitted OFDM is a multicarrier modulation technique for efficient and reliable data communication. This technique forces a major problem during the signal transmission process, which is a high peak-to-average power ratio (PAPR), leading to ...

PAPR analysis in OTFS using the centre phase sequence matrix based PTS method

Results in Optics
Orthogonal time–frequency space (OTFS) is a multicarrier modulation technique for high-speed data transfer in wireless communications. In an OTFS system, many subcarriers are used to send the modulated symbols. This makes OTFS signals have a high peak-to-

Chicken Swarm Optimization for PTS based PAPR Reduction in OFDM Systems

Journal of Communications Software and Systems, 2020
Partial transmit sequence (PTS) is a well-known PAPR reduction scheme for the OFDM system. One of the major challenge of this scheme is to find an optimal phase vector using exhaustive search over all the allowed phase factor combinations.
