Method For Retransmitting According To Receiving Channel Environment, Transmitter For The Same, Method And Apparatus For Generating Feedback Information

The present invention relates to retransmission method and transmitter, the feedback information generating method and apparatus for the same according to the received channel condition. According to the present invention will MIMO measurement (MIMO) received by group consisting of in the system of the number of sub-carrier or per predetermined transmission antennas subcarrier channel jeonryeokreul, to select an index having undergone a significant fading index and good channel, retransmission by exchange this map data, it is possible to improve the overall system efficiency. MIMO, fading
