Abstract:
In a multi-user multiple input multiple output (MIMO) communication system using the same radio resource, a unitary matrix may be generated to remove interference signals and enhance a transmission capacity. The unitary matrix may be used for precoding. Vectors included in the unitary matrix may have a most similar direction to precoding vectors of target terminal devices and may be orthogonal to each other.
