METHOD FOR TRANSMITTING SIGNALS IN THE SYSTEM WITH MULTIFUL ANTENNAS

摘要

A signal transmission method in a system using multi-antenna is provided to demodulate a reception signal and improve communication performance simply by transmitting a reception signal in a good condition. The first data symbol group including two or more data symbols is multi-antenna-encoded to form at least two same second data symbol groups. The same data symbols included in the at least two second data symbol groups are transmitted through each different transmit antenna. The second data symbol groups are formed by performing multi-antenna encoding on the first data symbol group according to an orthogonal design condition.
