摘要：
Disclosed is an apparatus for transmitting data in a communication system, including: a receiving unit configured to receive signals from multi-users by a multi-user-multi input multi output (MIMO) scheme and acquire channel information from the users; a calculation unit configured to calculate precoding vectors for the users using the channel information; a precoding unit configured to precode data of the users using the precoding vectors; and a transmitting unit configured to transmit the precoded data to users by the multi user-MIMO scheme.
