The high-order ambiguity function (HAF) was introduced for the estimation of polynomial-phase signals (PPS) embedded in noise.Since the HAF is a nonlinear operator, it suffers from noise-masking effects and from the appearance of undesired cross-terms when multicomponents PPS are analyzed.In order to improve the performances of the HAF, the multi-l
Front Selector Housing In order to verify accuracy of values of grounding insulation resistance and distributed capacitance of underground low-voltage power grid measured by AC voltammetry and AC-DC voltammetry, the paper introduced theory analysis and deduction of calculating formula of the two methods, and made comparison for measuring results of
The stanza in the sonnet has been defined as a set of poetic lines followed after proem and be the same meter as that of proem in complete stanza, but in rhyme scheme different from that meter.The couplet is defined as set of poetic lines that followed the stanza and be as the same meter as that of stanza, but with different rhyme scheme.This defin
