PROBLEM TO BE SOLVED: To compensate non-linear distortion due to multiple factors while restraining increase in a circuit scale.SOLUTION: A communication system 9 according to the invention comprises: a first device 91 that applies first processing to a transmission signal and transmits the transmission signal; and a second device 92 that applies second processing to the transmission signal transmitted by the first device 91. The second device 92 includes: a second storage unit 921 that has stored a second compensation coefficient that will be a compensation coefficient of non-linear distortion generated in the transmission signal by the second processing; and a second control unit 922 that obtains the second compensation coefficient and transmits it to the first device 91. The first device 91 includes: a first storage unit 911 that has stored a first compensation coefficient that will be a compensation coefficient of non-linear distortion generated in the transmission signal by the first processing; a first control unit 912 that obtains the first compensation coefficient, and the second compensation coefficient transmitted by the second device 92; and a first distortion compensation unit 913 that compensates the non-linear distortion of the transmission signal on the basis of the obtained first compensation coefficient and the second compensation coefficient. |
