Receiving Apparatus, Radio Communication System, Position Estimation Method and Program

摘要

There is provided a receiving apparatus including a plurality of receiving antennas, each of which receives a radio signal in which sub-carriers of different frequencies are multiplexed, a phase calculation unit that calculates a phase difference of each radio signal received by the plurality of receiving antennas from that of a reference signal for each of the sub-carriers contained in the radio signals, and a path difference calculation unit that calculates a path difference, which is a difference of distances from a transmitting antenna from which the radio signals are transmitted to any two receiving antennas of the plurality of receiving antennas, based on the phase difference calculated by the phase calculation unit.
