Homodyned k distribution
Webstrated that the k-distribution is a good model for the amplitude distribution of the received signal. A more generalized statistical model, the homodyned k-distribution, has been analyzed in [30].It combined the features of the k-distribution and Rice distribution to better account for the statistics of the signal.
