Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATION
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A wireless communication system for performing transmission by SC-MIMO between a transmission apparatus including a plurality of antennas and a reception apparatus including the number of antennas different from the number of antennas of the transmission apparatus,
wherein the transmission apparatus includes
a training signal generation unit configured to generate a known signal predetermined;
a CP addition unit configured to add a CP to at least one symbol of a transmission signal including the known signal; and
a transmission beam formation unit configured to use a transmission weight to form a transmission beam for the transmission signal where the CP is added,

the reception apparatus includes
a CP removal unit configured to remove the CP added to a reception signal;
a channel estimation unit configured to estimate a channel matrix based on the known signal; and
an equalization unit configured to perform equalization processing on the reception signal where the CP is removed, and

the transmission apparatus or the reception apparatus further includes
a weight generation unit configured to multiply the channel matrix by a pseudo-inverse matrix obtained by a predetermined number of iterative calculations to generate the transmission weight that is diagonalizable.
