A Practical Pilot for Channel Estimation of OTFS
(2023)The widely used embedded impulse pilot for channel estimation of orthogonal time frequency space modulation (OTFS) has a prohibitively large peak to average power ratio (PAPR). Hence, in this paper, we propose a novel ... -
Practical Synchronization for OTFS
(2023)In the existing literature on joint timing and frequency synchronization of orthogonal time frequency space modulation (OTFS), practically infeasible impulse pilot with large peak-to-average power ratio (PAPR) is deployed. ... -
Precession aided magnetic stochastic resonance in ferromagnetic nanoparticles with cubic anisotropy
(American Physical Society, 2005)It is shown that the signal-to-noise ratio in the magnetic stochastic resonance of single-domain ferromagnetic nanoparticles having cubic anisotropy exhibits a strong intrinsic dependence on the decay rate a of the ... -
Precessional effects in the linear dynamic susceptibility of uniaxial superparamagnets: Dependence of the ac response on the dissipation parameter
(American Physical Society, 2001)It is shown that the low-frequency relaxation spectrum of the linear dynamic susceptibility of uniaxial single domain particles with a uniform magnetic field applied at an oblique angle to the easy axis can be used ... -
Preparation and characterisation of metallorganic precursors derived iron oxides on porous silicon layers
(Trans Tech Publications Ltd., Switzerland, 2020)Porous silicon has generated interest in scientific community after its photoluminescence discovery and thereafter, research was focused on to the chemical functionalization of silicon and subsequent anchoring of nanoparticles ... -
The Price of Ignorance: Distributed Topology Control in Cognitive Networks
(2010)In a cognitive network, autonomous and adaptive radios select their operating parameters to achieve individual and network-wide goals. The effectiveness of these adaptations depends on the amount of knowledge about the ... -
