Abstract
We propose a low complexity technique to generate
amplitude correlated time-series with Nakagami-m distribution
and phase correlated Gaussian-distributed time-series, which is
useful in the simulation of ionospheric scintillation effects during
the transmission of GNSS signals. The method requires only
the knowledge of parameters S_4 (scintillation index) and sigma_phi (phase standard deviation) besides the definition of models for the amplitude and phase power spectra. The Zhang algorithm is used to produce Nakagami-distributed signals from a set of Gaussian autoregressive processes.
