A novel simulator for correlated generalized-K composite fading channels

A new simulator for correlated generalized-K (GK) composite fading channels was proposed, which is helpful on performance analysis of communication over this fading channels. It models the correlated GK fading channels by a series of Gamma random fadings with prespecified correlation matrix, which can be generated by well-established methods easily. The simulation results show that the new simulator has a good agreement with the theoretical one on fading envelope distribution and correlation characteristics.
