A receiver includes a channel estimation unit that calculates channel estimation values of symbols containing pilot signals from signals transmitted by a plurality of antennas to obtain channel estimation values of symbols in the same positions of the antennas, a de-precoding unit that de-precodes the channel estimation values of the antennas calculated by the channel estimation unit to calculate effective channel estimation values, and a time-direction interpolation unit that performs time-direction interpolation using the effective channel estimation values calculated by the de-precoding unit to calculate effective channel estimation values of symbols other than the symbols containing pilot signals.
