Cross-correlated Rayleigh fading processes play an important role in wireless communication simulation. In this paper, a novel and efficient model for the simulating cross-correlated Rayleigh fading channels is proposed. This model can generate the Rayleigh fading progress having a specified cross correlation from a number of uncorrelated standard Gaussian random progresses. Simulation results and computational complexity analysis are presented, which show that the proposed model with recursive algorithm have some advantages, such as high accuracy, low computational complexity and easy implementation, when compared with the conventional simulation model.
