%X In this paper, a modified sum-of-sinusoids statistical simulation method is proposed for Rayleigh channels. In some well-known methods, there exist problems that the probabiltiy density function (pdf) of the quadrature components and the squared envelope autocorrelation are nonstationary. It shows that the modified method can eliminate the above problems. It is proved in theory that the autocorrelations and cross correlations of the quadrature components and the autocorrelation of the complex envelope of the modified simulators match the desired ones exactly. Moreover, simulation results show that it has a better performance in terms of the probability density functions of the envelope and phase, the level crossing rate, and the average fade duration than the previous methods.
