Research on Peak‐to‐Average Power Ratio Control Method for Switched Reluctance Pulse Generator

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
Addressing the different requirements for peak output power when SRPG supplies power to pulse loads and DC loads, the peak‐to‐average power ratio (PAPR) is taken as the generation performance optimisation parameter. By investigating the power characteristics of the SRPG, the influence of control parameters on the PAPR is studied.

Spectrally Compatible Deceptive Jamming Waveform Design for Synthetic Aperture Radar Countermeasures

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This paper focuses on the design of synthetic aperture radar (SAR) deceptive jamming waveforms with spectrum‐compatible capability. By using the synthesised jamming waveform, successful deception against the hostile SAR system is demonstrated by generating false targets with high fidelity in both range and azimuth.

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

IEEE 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 ...

PAPR Reduction Scheme for OFDM

Procedia Technology, 2012
AbstractThis paper focused on peak to average power ratio (PAPR) reduction scheme for OFDM system. OFDM has several properties which make it an attractive modulation scheme for high speed transmission. the main draw back of OFDM is high PAPR. The high PAPR causes the interference and degraded the performance of the system while OFDM signal pass through

Space-Time Coded OFDM with Low PAPR [PDF]

EURASIP Journal on Advances in Signal Processing, 2006
Summary: Recently the use of multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems has been proposed for signaling over frequency-selective fading channels. Although various aspects of these systems have been considered in the literature, the problem of the inherent high peak-to-average power ratio (PAPR) is ...

Pilot‐Based Iterative Path Estimation and Maximum Ratio Combining (MRC)–Based Signal Detection of Orthogonal Time–Frequency Space (OTFS) Modulation for 6G in Fractional Doppler Channels

Journal of Computer Networks and Communications, Volume 2026, Issue 1, 2026.
The sixth generation (6G) wireless networks are used to provide a large coverage, and also this generation needed to support different emerging applications in harsh areas with higher user equipment mobility. For the above case, a new modulation technique called orthogonal time–frequency space (OTFS) modulation has emerged as a promising technique to ...

Impact of Hanks Kinase‐Dependent Phosphorylation of CodY on the Physiology and Virulence in Bacillus cereus

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
CodY is a global regulator whose phosphorylation at serine 215 by PrkC/YbdM alters its DNA binding, thereby modulating gene expression and impacting motility, biofilm formation, cytotoxicity, and pathogenicity in Bacillus cereus, suggesting a conserved regulatory mechanism in Firmicutes ABSTRACT CodY acts as a key regulatory protein involved in ...
