Performance of Quadrature OFDM System in Rayleigh Fading Channels
Journal of Engineering and Sustainable Development, 2011 This paper uses the Divide-and-Conquer DFT/IDFT computation approach instead of direct computation approach in OFDM system introducing a proposed system called Quadrature OFDM (Q-OFDM).

Titanium Suboxides Responsible for Electronic Anomaly Near Room Temperature in the Ti3C2Tx MXene
Advanced Functional Materials, EarlyView.Our multi‐technique study reveals that the near‐room‐temperature anomaly in Ti3C2Tx MXene is linked to titanium suboxide nanodomains, including Ti3O5, embedded within the MXene host. Their temperature‐driven transformation provides an alternative explanation to solvent‐ and swelling‐based models and offers new insight into the thermally activated ...

Advanced Functional Materials, EarlyView.Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights

Performance Analysis of MRC Diversity Reception Over Double Hoyt Fading Channels
IEEE AccessIn this paper, the performance of diversity systems operating in flat double Hoyt fading channels is studied. A novel exact expression, in the form of double finite-range integrals, is derived for the moment generating function (MGF) of the instantaneous

Advanced Functional Materials, EarlyView.In the work reported herein, dipole‐engineered sulfonated carbon nanofibers enable conductive additives to actively regulate interphase formation in silicon anodes. Polar sulfonyl groups guide electrolyte decomposition to form a compact LiF‐rich interphase while promoting robust integration with silicon.
