Nonlinear prediction of frequency-domain channel parameters for channel prediction in fading and fast Doppler-shift change environment

In this paper, we propose a frequency-domain channel prediction employing chirp z-transform and nonlinear parameter prediction. Simulation results demonstrate that the prediction accuracy remains very high even in fast Doppler-shift change environment. We find that the bit-error rate (BER) is lower than the previous linear prediction results in a series of simulations. The calculation cost is very small, i.e., almost the same as that in the previous linear prediction method.
