Abstract

The present invention relates to a transmission device and method using space-frequency transmission diversity in a communications system. The transmission device and method using space-frequency transmission diversity according to the present invention is characterised in that data or signals are grouped into 2 or more groups which are then transmitted through different transmission antennae by using different subcarriers.
