摘要
A transmitting station includes a plurality of transmitting weight multiplication units multiplying each of the transmission signal sequences by a transmitting weight, to be converted into MTX signals corresponding to UCAs forming an M-UCA so as to output the converted signals, and MTX transmitting OAM mode generation units inputting the signals corresponding to the UCAs and performing DFT on the input signals, so as to output to the corresponding UCA; and a receiving station includes MRX receiving OAM mode demultiplex units inputting signals from each of the UCAs forming the M-UCA and performing IDFT on the input signals, so as to output by each of received signal sequences, and a plurality of receiving weight multiplication units multiplying for each of them by a receiving weight, so as to demultiplex the spatially multiplexed received signal sequences and to output them in which interference between spatially multiplexed OAM modes is suppressed.
