Abstract:
1. An apparatus to cancel inter-antenna interference, the apparatus comprising: a reception unit configured to receive, from a transmitter, first data and second data orthogonally coded with the first data, and to generate a received vector including the first data and the second data; a channel estimation unit configured to generate a channel state matrix with respect to a radio channel from a plurality of transmission antennas of the transmitter to the reception unit; a detection unit configured to detect the first data based on the channel state matrix and the received vector; a pseudo interference signal-generation unit configured to generate pseudo interference signals based on the channel state matrix and the detected first data; and an interference signal-canceling unit configured to cancel the pseudo interference signals from the received vector, wherein the detection unit detects the second data based on the received vector from which the pseudo interference signals are cancelled.
