<p>PROBLEM TO BE SOLVED: To reduce an amount of calculation when an impulse response for a multi-path propagation path is estimated by use of compression sensing.SOLUTION: A receiver receives a frame including a pilot signal and a data signal, and performs a compensation process for the data signal with reference to an impulse response for a propagation path estimated from the pilot signal. The receiver comprises: an extracting part that extracts the pilot signal of the frame; and an estimating part for executing OMP (Orthogonal Matching Pursuit) method, which is a decryption algorithm for compression sensing, and estimating an impulse response for the propagation path from the pilot signal. The estimating part estimates an impulse response by referring to the pilot signal of the first frame, calculates position information for the estimated impulse response, estimates an impulse response by referring to a pilot signal corresponding to the position information among the pilot signals of a second frame following the first frame, and calculates the position information for the estimated impulse response.</p> |
