Abstract

The data transmission method using transmit diversity according to one aspect of the present invention enables a permutation matrix to be used without any feedback regarding channel status from a receiver to switch an antenna whereat each stream is re-transmitted, and comprises: a step wherein streams to be transmitted to each antenna are used to configure a frame; a step wherein at the frame cycle setup, a permutation is applied to the frame or all the burst included in a specific zone of the frame to switch an antenna whereto each stream included in the frame or the entire burst is transmitted; and a step wherein the frame is transmitted through each antenna.
