PURPOSE: A system for transmitting and receiving a CSi is provided to enable a transmitter to solve a problem which can obtain a CSI. CONSTITUTION: A precoding module(102) removes a channel interference of a receiver. An IFFT(inverse fast Fourier transform) module(103) modulates the precoded signal into a multiplex subcarrier OFDM. An orthogonal sequence set module(114) obtains a channel matrix of each orthogonal permutations and redundancy antenna for estimating a channel. A channel estimation module presumes an uplink channel matrices by using an orthogonally of orthogonal permutations. A channel combining module unites channel matrixes of the redundancy antenna. |
