ABSTRACT:
A method for transmitting signal in a mobile communication system allocates symbols which will be transmitted to transmitting antennas appropriately as considering detection efficiencies of symbols on a higher order modulation constellation and correlation between antennas, and thereby independent symbol transmission can be made and independence between antennas can be improved to improve accuracy of symbol detection on a receiving end and signal transmitting function of the system can be improved. Therefore, a pair of symbols having the longest distance between symbols is arranged to a pair of antennas having higher correlation and a pair of symbols having the shortest distance between symbols is arranged to a pair of antennas having lower correlation. Also, symbols having higher detection efficiency are allocated to antennas having higher correlation and symbols having lower detection efficiency are allocated to antennas having lower correlation.
