In the context of this paper, a maximum value of the envelope correlation is indicative of an optimum alignment between the (m+1 th reference profile rm +1(n) and the shifted range profile pm +1(n−τ m +1).
At t = 0 s, when the signal envelope reaches its maximum, the travel time curve from source A samples the maximum of the signal envelope at all stations and leads to a maximum stack.
where cmax is the maximum of the signal envelope c(n).
However, their data do not appear to be conclusive: inspection of their Fig. 9(d) shows that whilst there is what they describe as a ' local maximum' at s = 1 (the reader is referred to their paper for the meaning of ' s'), the maximum of the peak envelope is at s > 1, which would mean that Al was absent from the third shell, which would support the hexagonal supercell rather than orthorhombic.
However, in some cases, the effect of residual range-dependent motion error could be neglected if the maximum of RCMC envelope is within 1/4 rang bin, which is shown as: max left| {Delta {R_{ E} + frac{{rsin varphi }}{{{{cos }^{2}}varphi }} cdot frac{{partial Delta {R_{E}}}}{{partial X}}} right| le frac{1}{4}Delta r (33).
A local maximum in the differential of the envelope corresponds to a strong rise in the envelope itself.
If Eq. (5) is integrated twice, the maximum velocity of the expanding envelope, corresponding to the initial ejection velocity, v i, in the trajectory model, is obtained.
However, even at the maximum, the envelope fluctuations of B-IFDMA are considerably lower than for a corresponding scheme without DFT precoding.
Indirect formant positions are determined as the first three local maxima of the smoothed spectral envelope where its gradient changes from positive to negative.
We apply the approach combining two basic methods for formant position determination (see Figure2). 1. Indirect formant positions are determined as the first three local maxima of the smoothed spectral envelope where its gradient changes from positive to negative.
