A null is to be directed even to layers in which the locations of reference signals are not physically multiplexed. A reception apparatus (10) of the present invention comprises: adaptive array antennas (11) that receive space-multiplexed signals; a reference signal combination unit (15) that multiplies the reference signal parts of the layers of the space-multiplexed signals by an orthogonal signal, combines the reference signal parts having different resource elements and adjacent to each other, thereby calculating a combined reference signal, and further multiplies a known reference signal by the orthogonal signal; a weight calculation unit (16) that calculates, from the combined reference signal and the known reference signal having been multiplied by the orthogonal signal, an adaptive array weight; a weight combination unit (17) that multiplies the reference signal parts by the adaptive array weight, thereby performing an antenna combination to calculate a combined received signal; a channel estimation unit (18) that estimates a propagation path from the combined received signal and the known reference signal having been multiplied by the orthogonal signal; and a channel equalization unit (19) that executes a channel equalization from the combined received signal and the propagation path. |
