Fabrication and characterization of TiO2 nanoparticles conjugated luminescence upconversion nanoparticles
(Open Access Journal, 2018)
TiO2 nanoparticles conjugated luminescence upconversion (TiO2-UC) nanocomposites have been fabricated by covalently linking of carboxyl-functionalized TiO2 and amino-functionalized NaYF4:Yb3+,Er3+,Ce3+ upconversion ...
A non-resonant kinetic energy harvester for bioimplantable applications
A linear non-resonant kinetic energy harvester for implantable devices is presented. The design contains a metal platform with permanent magnets, two stators with three-dimensional helical coils for increased power generation, ...
CP-less OFDM with alignment signals for enhancing spectral efficiency, reducing latency, and improving PHY security of 5G services
(IEEE Access, 2018)
Although orthogonal frequency-division multiplexing (OFDM) is a widely accepted waveform in many standards and is expected to keep its dominance in future 5G systems with various types of parameterized waveforms, its ...
Joint PHY/MAC layer security design using ARQ with MRC and null-space independent PAPR-aware artificial noise in SISO systems
(IEEE Transactions on Wireless Communications, 2018)
Automatic-repeat-request (ARQ) as a MAC layer mechanism and artificial noise (AN) as a physical layer mechanism along with the help of maximal ratio combining (MRC), are jointly designed to achieve secrecy. Basically, a ...
(MDPI AG, 2018)
Statistical relationships among the variables of a complex system reveal a lot about its physical behavior. Therefore, identification of the relevant variables and characterization of their interactions are crucial for a ...
