Incoherent hopping
WebIt first discusses the compressive sampling model, FH-BPSK (frequency hopping binary phase-shiftkeying) modulation signal model and its sparsity. Then, it focuses on the RIP (Restricted Isometry Property) and incoherent properties of measurement matrix in digital domain compressive sampling, as well as noise folding caused by compressive sampling. WebAbstract We assess the validity of incoherent hopping models that have previously been used to describe electron transport in crystalline C 60 at room temperature. To this end we present new density functional theory based calculations of the electron transfer parameter defining these models.
