Feeding back antenna shuffling information in a multiple-input multiple-output system using a multiple space-time block coding technique and a method therefor

摘要

In a method for feeding back combination information of transmitted signals in a multiple-input multiple-output (MIMO) system using a multiple space-time block coding technique, mean square error values are computed in relation to the combination information pieces of the transmitted signals. An index of a combination having a minimum mean square error value from among the mean square error values is fed back.
