Rayleigh fading due to multipath propagation in wireless channels is widely modelled using sum-of-sinusoids simulators. In particular, Jakes' simulator and derivatives of Jakes' (1994) simulator have gained widespread acceptance. Despite this, few in-depth studies of the simulators' statistical behaviours have been reported in the literature. Here, the extent to which Jakes' simulator adequately models the multipath Rayleigh fading propagation environment is examined. The results show that Jakes' simulator does not reproduce some important properties of physical fading channels.
