Summary:
This article proposes a convolutional neural network (CNN) aided SNR estimation method using IQ constellation images. CNN can extract features including the influence of power and phase variation from the received signal constellation. The simulation experiment shows that the proposed method is more tolerant of Doppler shift than the conventional error vector magnitude (EVM) based estimation.
