초록
In this paper, an cost-effective system architecture is proposed to implement digital predistortion scheme for linearizing the PA amplifing TDD wideband signal. To make digital predistorted signal for compensating nonlinearity of PA, a dedicated ADC and a frequency-down converter are necessary. Proposed scheme is based on the TDD feature that the RF receiver frontend is idle state during the downlink signal processing time and utilize them to make the digital predistorted signal for PA.
