Abstract: Embodiments of the present invention disclose a microwave predistorted signal generating method and apparatus. A microwave receiver receives a first received signal that has undergone analog-to-digital conversion; performs channel compensation on the first received signal, to obtain a second received signal; estimates a first transmitted signal according to the second received signal, where the first transmitted signal is a transmitted signal of a microwave transmitter before digital-to-analog conversion; performs predistortion coefficient computation according to the second received signal and the first transmitted signal; performs, by using a first-order coefficient obtained through the predistortion coefficient computation, linear distortion compensation on the second received signal that is before the first transmitted signal is estimated; and sends other predistortion coefficients except for the first-order coefficient to the microwave transmitter, so that the microwave transmitter performs non-linearity predistortion on a transmitted signal.
