Abstract :
For original paper see Tsai et al. (IEEE Commun. Lett., vol.6, p.178-80, 2002 May). This comment points out three inaccurate formulae and the problems in results of the numerical simulations. The correct formulae and results of the voltage correlation coefficients are provided. Our simulations have shown the simulation results exhibit good agreement with the analytical results as long as the items of the series expansion long enough.
