— This paper applies the level crossing rate (LCR) and average fade duration (AFD) analysis to characterize clipping noise in filtered OFDM signals. Because orthogonal frequency division multiplexing (OFDM) signals exhibit complex Gaussian process behavior, well established results for the Rayleigh envelope of the correlated Gaussian process are used to(More)
Introduction Alzheimer's disease (AD) neuropathology is characterized by key features that include the deposition of the amyloid-beta peptides into senile plaques, the formation of neurofibrillary tangles, and the loss of neurons and synapses in specific brain regions. Here we report a measure of AD evolution based on the use of MR images of the APP(More)
