Abstract:
Embodiments of the present disclosure provide a digital predistortion processing apparatus, where the apparatus includes an analog-to-digital conversion unit and n digital predistortion elements. The analog-to-digital conversion unit is connected to the n digital predistortion elements. Each digital predistortion element is configured to receive n input signals, perform digital predistortion processing on the n input signals, and then output n processed signals. The analog-to-digital conversion unit is configured to receive the n processed signals, perform signal extraction based on the n processed signals, and output an extracted signal, where a rate of the extracted signal is the same as a rate of each of the n processed signals. For an ultra-large-bandwidth signal, DPD correction may be performed without increasing a technical level of existing components such as an FPGA and an ADC, thereby greatly reducing implementation costs.

Claim (Index 7):
The apparatus according to  claim 1 , further comprising:\n n crest factor reduction elements each having an output end separately connected to the input ends of each digital predistortion element, and wherein each crest factor reduction element is configured to receive one original input signal, perform crest factor reduction processing on the original input signal to obtain the input signal, and send the processed input signal to the n digital predistortion elements.
