Abstract:
1. A phase noise limiting apparatus comprising: detecting means for detecting a phase noise quantity from an input signal; determining means configured such that furnished with a plurality of correspondence tables indicating parameters used for phase synchronization with said input signal, said determining means determines one of said parameters in keeping with said phase noise quantity detected by said detection means on the basis of one of said plurality of correspondence tables, wherein the phase noise quantity detected with regard to the phase noise to be limited varies among a plurality of down-converter types, wherein each of the plurality of down-converter types comprises a corresponding correspondence table, wherein each of the plurality of correspondence tables indicates a loop gain deemed optimal for limiting the phase noise in a detected quantity of each of the plurality of down-converter types; and phase noise limitation means for limiting the phase noise in said input signal based on the parameter determined by said determining means.
