PROBLEM TO BE SOLVED: To provide a method of processing data capable of improving a signal quality in an MIMO system. SOLUTION: The method of processing data includes dividing user terminals into groups based on channel characteristics and QoS requirements of the user terminals, and further includes a step A of setting a corresponding precoding code word and cyclic delay for each of the groups and a step B of determining a group to which the user terminal corresponding to a processing object data belongs and subjecting the processing object data to the cyclic delay diversity (CDD) precoding processing applying the precoding code word and cyclic delay corresponding to the relevant group. In addition, the present invention discloses a device for processing data. The device includes a grouping module and a cyclic delay diversity (CDD) precoding processing module.
