The differential chaotic shift keying(DCSK) communication in multiple input multiple output(MIMO) multipath fading channels is considered. A simple MIMO-DCSK co
Hexagonal NaYF4:Yb3+,Er3+ (β-NaYF4:Yb3+,Er3+) nanoparticles supported on TiO2 nanobelts were prepared using two-step procedures of ion-exchangeable process and
Using density functional methods, some properties were studied such as the energies and compositions of frontier molecular orbitals and the atomic charges, whic
For global navigation satellite system(GNSS) signals in Gaussian and Rayleigh fading channel, a novel signal detection algorithm is proposed. Under the low freq
