RECEIVING APPARATUS, RECEIVING METHOD, COMMUNICATION SYSTEM, AND COMMUNICATION METHOD

摘要

This receiving apparatus is provided with: a first frequency response estimation unit which calculates a first frequency response estimated value by means of a reference signal; an interval extraction unit which extracts at least one interval from among candidate intervals obtained by dividing a predetermined maximum delay time into a plurality of intervals and determines an estimated interval; and a second frequency response estimation unit which calculates a second frequency response estimated value, which is a demodulation frequency response estimated value, on the basis of the first frequency response and the estimated interval. Thus, a receiving apparatus can be provided which is capable of accurately estimating a propagation path even if various power delay profiles (PDPs) are taken over time.
