Reducing the Peak to Average Power Ratio of UFMC Waveform for Beyond 5G System Using Hybrid SLM+PTS+RNN Algorithms

IET Communications, Volume 19, Issue 1, January/December 2025.
This article proposes a hybrid SLM+PTS+RNN algorithm to mitigate the high PAPR challenge in UFMC systems for B5G networks. The method significantly improves power efficiency (by 30%–40%) while maintaining BER and PSD performance, outperforming traditional PAPR reduction techniques.

Two-step resource allocation for BIC-UFMC wireless communications

2016 International Symposium on Wireless Communication Systems (ISWCS), 2016
This paper outlines an efficient resource allocation (RA) algorithm for packet-oriented Universal Filtered Multi-Carrier (UFMC) communications with bit interleaved coded (BIC) modulation. Assuming perfect synchronization and perfect knowledge of the channel, the proposed RA strategy optimizes the coding rate, bit loading and power distribution within ...

A Beyond 5G OTFS Waveform Radio for Smart Hospital: PAPR Reduction in OTFS Using the Cuckoo Search–Based PTS Method

Journal of Electrical and Computer Engineering, Volume 2025, Issue 1, 2025.
Smart hospitals have enormous potential to improve global standards of medical services. Integrating fifth‐generation (5G) and beyond 5G radio with the present healthcare framework can make hospitals smarter. High spectral access, data rate, capacity, low latency, and large data handling are requirements of innovative hospitals.

Design of Waveform Shaping Filter in the UFMC System

IEEE Access, 2018
The universal filtered multi-carrier (UFMC) has been taken as a promising candidate for future wireless communication, where a finite impulse response filter is employed to shape the waveform and enhance its resistance to inter-carrier interference.

Entanglement and teleportation in quantum key distribution for secure wireless systems

IET Quantum Communication, Volume 5, Issue 4, Page 551-566, December 2024.
A quantum entanglement‐aided and teleportation‐based quantum key distribution system is proposed. The proposed protocol uses quantum Fourier transform for its implementation. The proposed protocol can provide enhanced security to wireless systems measured in terms of quantum bit error rate, secure key rate, and reconciliation efficiency.

The response of high-impact blocking weather systems to climate change [PDF]

, 2016
Mid-latitude weather and climate are dominated by the jet streams and associated eastward-moving storm systems. Occasionally, however, these are blocked by persistent anticyclonic regimes known as blocking.

Synthesis, DFT calculations, and investigation of catalytic and biological activities of back‐bond functionalized re‐NHC‐Cu complexes

Applied Organometallic Chemistry, Volume 38, Issue 7, July 2024.
re‐NHC‐Cu complexes have been synthesized and used as catalyst on CuAAC reactions. Five copper complexes (3a–e) stabilized by ring‐expanded back‐bond functionalized N‐heterocyclic carbene ligands (re‐NHCs) were produced in the glovebox by reacting free re‐NHC with CuI precursor.

Stream Nitrogen, Phosphorus, and Sediment Concentrations Show Contrasting Long‐term Trends Associated with Agricultural Change

Journal of Environmental Quality, Volume 47, Issue 6, Page 1513-1521, November-December 2018., 2018
Stream water quality can be greatly influenced by changes in agricultural practices, but studies of long‐term dynamics are scarce. Here we describe trends over 21 yr (1994–2014) in nutrients and suspended sediments in three streams in a Midwestern US agricultural watershed. During this time, the watershed experienced substantial changes in agricultural
