Abstract
An apparatus for use in a polar transmitter to perform distortion estimation and compensation is provided. The apparatus includes a mixing unit, a signal processing unit, an estimation unit and a compensation unit. The mixing unit is configured to mix a test output signal and a frequency down-converting signal to generate a mixed signal. The processing unit is configured to perform signal processing on the mixed signal to generate a processed signal. The estimation unit is configured to perform distortion estimation on the processed signal to generate a distortion estimation result. The compensation unit is configured to perform pre-distortion compensation on input signals of the polar transmitter according to the distortion estimation result.
