Mimo communication method, transmitting device, and receiving device

摘要

A Multiple Input Multiple Output (MIMO) communication method and system for performing communication between N, N is an integer greater than or equal to 2, transmitting devices (110 to 140) each having a transmit antenna and at least one receiving device (200) having N receive antennas (211 to 241) by using a multi-user MIMO scheme. The method includes dividing the N transmitting devices into a plurality of sets, and assigning an orthogonal code to each set of transmitting devices as a digital signal sequence to be transmitted by each of the transmitting devices, and arranging the digital signal sequences to be transmitted by the transmitting devices in a frequency axis direction in which an inverse fast Fourier transform is performed, and performing coding.
