This OAM multiplexed communication system performs multiplex transmission on one or more sequences of signals for each OAM mode and is provided with: a transmission station provided with transmission antennas using M-UCAs and an OAM mode generation means for simultaneously generating one or more OAM modes from each UCA; and a receiving station provided with receiving antennas equal to the M-UCAs, an OAM mode separation means for separating, for each OAM mode, signals received by each UCA, and a channel estimation/interference compensation processing means for estimating a channel matrix for each OAM mode and compensating for inter-OAM interference by using weights, wherein, for each OAM mode, the channel estimation/interference compensation processing means selects signals in an own mode and an adjacent mode from among signals in each OAM mode separated by the OAM mode separation means, and compensates for the inter-mode interference by multiplying approximate weights calculated by using the channel matrices of the own mode and the adjacent mode thereto.
