Hidden Markov model technique for dynamic spectrum access
Dynamic spectrum access is a paradigm used to access the spectrum
dynamically. A hidden Markov model (HMM) is one in which you
observe a sequence of emissions, but do not know the sequence of states, the model went through to generate the…

Improving color rendering index of WLEDs with convex-dual-layer remote phosphor geometry using red-emitting CaGa2S4:Mn2+ phosphor
The white-light light-emitting diode (LED), a conventional illumination
solution, usually consists of one chip and one phosphor layer, which leads to the insufficient color rendering index (CRI) in this configuration. To optimize the efficiency of…
