Patent ID: 8331474

Claim:
A wireless communication system, comprising: a transmission apparatus comprising: an orthogonal processor operable to perform orthogonalization processing based on the orthogonality of wireless resources to each of signal sequences so that symbol series of each time obtained from each of a plurality of transmission streams are orthogonalized, the signal sequences being obtained by dividing each of the plurality of transmission streams; and a transmitter to transmit each of the signal sequences being subjected to the orthogonalization processing through multiple antennas, wherein symbols of each of the signal sequences are respectively based on a same symbol of the plurality of transmission streams; and a reception apparatus comprising: an orthogonal separator operable to perform orthogonal separation processing based on the orthogonality to a signal received from the transmission apparatus to separate the received signal into a plurality of reception signal sequences having an orthogonal characteristic therebetween; and a signal separator operable to apply a predetermined signal separation method based on a propagation path estimation matrix between the reception apparatus and the transmission apparatus to any of the pairs of the plurality of reception signal sequences to regenerate the signal sequences before being subjected to the orthogonalization processing.
