New sum-of-sinusoids simulation models are proposed for Rayleigh fading channels and compared with existing simulation models. First, an ergodic statistical ("deterministic") model is proposed that, compared to existing models, yields a significantly lower cross-correlation between different complex envelopes and between the quadrature components of each complex envelope. However, the auto-correlation functions of the quadrature components still do not match the theoretical functions. To overcome this disadvantage, we also propose a new statistical simulator that converges faster than existing statistical models, and has lower cross-correlations between different complex envelopes and between the quadrature components of each complex envelope. This new statistical model yields adequate statistics with only 30 simulation runs
