Abstract
A receiving apparatus includes a memory that stores parameters corresponding to lines based on a first time interval and a second time interval in a coordinate space in which first phase rotation in a reception signal is defined as a first axis and second phase rotation in a reception signal is defined as a second axis; a selecting device that selects a line that is closest to a coordinate point in the solution space, the coordinate point being represented by a first observation value of the first phase rotation and a second observation value of the second phase rotation; an acquiring device that acquires the parameters corresponding to the line from the memory; and an estimating device that estimates, based on the parameters, the first observation value, and the first time interval or the parameters, the second observation value, and the second time interval, frequency deviations of the reception signals.
