Abstract  Abstract

A method for receiving modulation signals includes receiving a plurality of multiplexed modulation signals each transmitted from multiple antennas of a communication partner wherein each modulation signal includes a pilot symbol sequence consisting of plural pilot symbols used for demodulation. Each of the pilot symbol sequences is inserted at the same temporal points in the each modulation signal. The pilot symbol sequences are orthogonal to each other with zero cross correlation among the plurality of modulation signals each pilot symbol having a non-zero amplitude the quantity of the plural pilot symbols in each sequence being greater than the quantity of the plurality of transmitted modulation signals. The method further includes estimating a transmission path distortion of the each modulation signal based on the plurality of received multiplexed modulation signals; and demodulating the each modulation signal including the plurality of received multiplexed modulation signals using the transmission path distortion.
