Apparatus and method of space time block code for increasing performance

Transmission of the present invention, a plurality of (e.g. three) (three for example) a plurality of by that, a predetermined symbol sequence is input rule on the space-time-frequency block coding apparatus in a transmitter of a communication system using transmission antenna in order to improve the performance of [received channel quality, for example, (Signal to Noise Ratio) SNR] of the space-time-frequency block code in a method for transmitting via the antenna using the feedback information sent by the receiver, or the matrix with a set of rules on its own It relates to the use of the device. Space-time-frequency block coding, feedback information, performance
