Title:
SIGNAL PROCESSING METHOD AND RECEIVER
Document Type and Number:
WIPO Patent Application WO/2021/203670
Kind Code:
A1
Abstract:
The present application provides a signal processing method and a receiver. In the present application, under different gear information, a receiver may pre-determine nonlinear coefficients of an input signal undergoing nonlinear distortion in the receiver, and generates correspondences between the nonlinear coefficients and receiver settings. The receiver may determine a nonlinear coefficient according to gear information, and thus according to the nonlinear coefficient, performs nonlinear compensation on an analog signal which is actually received. In this way, by adjusting gains of devices of the receiver, a signal-to-noise ratio of the receiver is optimized, so that the linearity and signal-to-noise ratio of the receiver can both reach a good effect, and the EVM performance of the receiver is improved.
