N2 - In radio frequency (RF) receiving units, predistortion technology is an effective means to address nonlinear distortion. This paper focuses on the in-band nonlinear response of single modulated signals in RF receiving units and uses the error vector magnitude (EVM) to evaluate the nonlinear effects. Regarding the limitation of traditional EVM testing methods and the problems in parameter acquisition in the spectrum-correlation-based method, this paper simplifies the testing process and introduces a convenient approach to accurately estimate the transfer function. Simulations show that the proposed method generates consistent results with the traditional method without prior knowledge of the transfer function of the device-under-test, which verifies its effectiveness.
