PURPOSE: A device for transmitting/receiving data optimally applied to various channel states in a CDMA mobile communication system including an antenna array and a method therefor are provided to divide transmission data into information bits and surplus bits only, and to transmit the information bits through a good transmission antenna, then to transmit the surplus bits through a bad transmission antenna, thereby increasing system performance. CONSTITUTION: The first distributor(66-1) distributes an interleaved bit string having the first importance into many bit strings by corresponding to the number of antennas(72,74,76,78). The second distributor(66-2) distributes interleaved bits having the second importance into many bit strings by corresponding to the number of the antennas(72,74,76,78). A multiplexer and modulator(68) multiplexes the bit strings distributed from the first and second distributors(66-1,66-2), modulates the multiplexed bit strings, and outputs modulation symbol strings as many as the antennas(72,74,76,78). A transmission antenna assigner(70) transmits each of the outputted modulation symbol strings through the corresponding antennas(72,74,76,78).
