System and method for transmitting/receiving signal in a mobile communication system using a multiple input multiple output (MIMO) scheme

摘要

Disclosed is a mobile communication system using a Multiple Input Multiple Output (MIMO) scheme. A transmitter of the mobile communication system, generates a unitary space-time matrix to correspond to a codeword if the codeword to be transmitted in a first time interval is input, multiplies the unitary space-time matrix by a first final transmission matrix denoting signals transmitted in a second time interval before the first time interval, thereby generating a second final transmission matrix denoting signals to be transmitted in the second time interval, and transmits signals corresponding to the second final transmission matrix through a plurality of transmit antennas in the second time interval.
