Abstract
In a communication system adapted to MIMO transmission, a receiver may include a filter to filter signals received from a transmitter through the receiver antennas and having a weight matrix thereof updated by an adaptive algorithm with respect to each substream message symbol from the transmitter, and a code generator to feed back a part of the weight matrix updated by the filter, as an updated STF code, to the transmitter. The transmitter may make the transmission using the updated STF code which is optimized for a current channel state.
