<P>PROBLEM TO BE SOLVED: To provide a transmission device capable of compensating distortion with high precision through a simple configuration. <P>SOLUTION: The transmission device includes a plurality of exciters which are made redundant, a predistortion type amplification part which amplifies an output signal from an in-use exciter functioning as an in-use system to a transmission level, and a branch part which branches the output of the amplification part and feeds a branch signal back. The plurality of exciters each include a compensation part. The compensation part compensates distortion generated at the amplification part by deforming characteristics of an input signal input to the exciter to reverse characteristics of gain characteristics of the amplification part. Further, the transmission device includes a data generation part. The data generation part generates information on which the gain characteristics of the amplification part are reflected based upon the fed-back branch signal, and supplies the information to the in-use exciter. <P>COPYRIGHT: (C)2013,JPO&INPIT |
