An information processing device includes: a user information acquisition unit which acquires first information, second information, and third information about a user; a correlation information acquisition unit which acquires correlation information representing a relation between the first information, the second information, and the third information; an initial value setting unit which sets an initial value of the first information, the second information, and the third information; a fixing designation unit which designate fixing of the first information; a change designation unit which designates change of the second information; and an update unit which updates the third information on the basis of the correlation information.

Information processing device and information processing method

A coherent integration section synthesizes an IF signal stored in a memory and a C/A code replica generated by a code generation section using a mixer to calculate a correlation value, and integrates the correlation value using an integration section. An integration count monitoring section counts the integration count of the integration section. When a saturation control section has detected saturation of integration of the correlation values, the integration count monitoring section causes the integration section to suspend integration when the integration count is equal to or less than a reference count, and allows the integration section to continue integration when the integration count has exceeded the reference count.
