摘要：A method and circuit that gives a sequence pattern that represents directionsof positive and negative transitions of the phase that continue over a predetermined

number from a certain reference symbol to an adjoining next reference symbol; finds(heuristically) one or more interpolate symbols that meet conditions (such as standardsfor power spectra) of a predetermined frequency spectrum, i.e., band, and a

predetermined (range of) amplitude with reference to the given sequence pattern; andstores the found sequence pattern and a phase value and an amplitude value

corresponding to the found one or more interpolate symbols in a memory as a lookuptable against the prepared memory area.
