APPARATUS AND METHOD FOR TRANSMITTING AND RECEIVING DATA USING SPACE-TIME BLOCK CODING

摘要

An space-time-frequency block coding (STFBC) apparatus for a transmitter with four Tx antennas is provided. An input symbol sequence is transmitted through the four Tx antennas in a predetermined method based on feedback information received from a receiver or a selected matrix with regularities, thereby improving the performance of an STFBC.
