Abstract

[Object] To generate a signal pattern generation apparatus capable of performing suitable processing even when an abrupt increase in the number of accesses occurs while the number of accesses is large, having an adequate long-tail characteristic, and capable of providing adequate fractality with respect to a plurality of ranges with respect to time and providing a suitable short-range distribution characteristic. [Solution] A signal pattern generation apparatus of the present invention is constituted by a root signal generation sectionwhich generates a root signal of a long-tail distribution having positivity, a statistical self-similarity signal generation section SSSSG which generates a statistical self-similarity signal based on wavelet analysis from the root signal, a general-filter sectionwhich decomposes the statistical self-similarity signal into at least two intermediate patterns, a coefficient acquisition sectionwhich obtains coefficients for the two intermediate patterns, and a resynthesis sectionwhich generates a resynthesized pattern from the two intermediate patterns and the obtained coefficients.
