Summary:The embodiment of the invention discloses a method and a device for data transmission, wherein, the method comprises the steps that: the link performances of different modulation code combinations are compared; according to the results of the comparison, a modulation code combination with the best link performance is selected from the modulation code combinations so as to carry out data transmission. The device comprises a comparing unit used for comparing the link performances of different modulation code combinations; a selecting and transmitting unit used for selecting a modulation code combination with the best link performance from the modulation code combinations according to the results of the comparison so as to carry out the data transmission. During the data transmission, the technical proposal adopted by the embodiment of the invention selects a modulation code combination which is most suitable for the channel transmission by comparing the link performances of different modulation code combination
