Embodiment 1
[0043] see figure 1 , a method for implementing signal predistortion processing in Embodiment 1 of the present invention, the method comprising:
[0044] Step 101: Utilize the feedback signal to update the predistortion parameters;
[0045] Specifically, the updating predistortion parameters may include but not limited to:
[0046] S101: Using a feedback signal to determine a predistortion coefficient;
[0047] Among them, because the prior art only performs simple gain adjustment on the feedback signal fed back by the power amplifier, and does not modify the feedback signal, which greatly affects the effect of digital pre-distortion processing; therefore, in this embodiment, it is proposed to determine The pre-distortion coefficient is firstly to modify the feedback signal, and then determine the pre-distortion coefficient by performing the orthogonal decomposition recursive least squares operation on the matrix composed of the modified feedback signal and the intermediate ...
