Frequency domain linear prediction (FDLP) is a technique for auto-regressive modeling of Hilbert envelopes. In this letter, the resolution properties of the FDLP model are investigated using synthetic signals with impulses immersed in noise. The effect of various factors are studied which affect the temporal resolution and this analysis suggests ways to improve the resolution of the FDLP envelo...

A novel precise radar target ranging method based on echo phases and slip matching of envelopes is presented in this paper. The method provides a high precision with rootmean-square error at sub-wavelength level, and it only requires envelopes of the echo pulses. The difficulty is matching procedure of envelopes. According to the principle of resolving ambiguous phases based on slip matching of...

Recent studies have shown that central nervous system neurons in weakly electric fish respond to artificially constructed electrosensory envelopes, but the behavioral relevance of such stimuli is unclear. Here we investigate the possibility that social context creates envelopes that drive behavior. When Eigenmannia virescens are in groups of three or more, the interactions between their pseudo-...

Several results have been reported in the literature on the performance of various diversity combining schemes for wireless communications systems. Typically for convenience it is assumed that the signal envelopes in the diversity branches are uncorrelated with one another. However, in practice the envelopes will be correlated. In this paper a procedure to generate two equal power Rayleigh fadi...

We introduce a new class of problems: computing the set of all the convex combinations of sites when their position is uncertain and depends linearly on shared parameters which vary according to a uniform distribution. The boundary of the set, called the uncertainty envelope, is useful in optimizing processes where there is uncertainty on the site positions and the objective functions. We provi...
