Most temporal signals of practical interest are nonstationary and need to be modeled using time-varying systems. In this paper a composite model for these signals is proposed which accounts for nonstationarities in the mean and the autocorrelation functions. Unbiased and consistent time-varying esti

Doppler ultrasound is used clinically to detect stenosis in the carotid artery. The presence of stenosis may be identified by disturbed flow patterns distal to the stenosis that cause spectral broadening in the spectrum of the Doppler signal around peak systole. This paper investigates the behaviour

AI~STRACT : A generalized category of cone-shaped kernels is proposed. Analysis of the kernel in the 2-D time, 2-D frequency, and ambiguity domains is pet;formed. The shape of this kernel in the 2-D time plane is bow-tie, which effectively suppresses cross-terms especially in the frequency direction
