1. A method of performing a pre-distortion calculation on an input signal of a frequency band spanning over a first frequency section and a second frequency section, performed by a device, the method comprising:
obtaining a first matrix corresponding to the first frequency section, a second matrix corresponding to the second frequency section, and a matrix corresponding to the frequency band based on a center frequency of the frequency band;
obtaining a first vector corresponding to the first frequency section, a second vector corresponding to the second frequency section, and a third vector corresponding to the frequency band based on the center frequency of the frequency band; and
performing pre-distortion on the input signal by using a coefficient matrix obtained based on the obtained matrix corresponding to the frequency band and the obtained third vector,
wherein the obtaining of the matrix corresponding to the frequency band comprises:
obtaining a first temporary matrix based on a first center frequency in the first frequency section, the center frequency of the frequency band, and the first matrix;
obtaining a second temporary matrix based on a second center frequency in the second frequency section, the center frequency of the frequency band, and the second matrix; and
obtaining the matrix corresponding to the frequency band by performing a calculation of summing the first temporary matrix and the second temporary matrix.
