The present invention discloses a method for predicting fast fading using sinusoidal modeling techniques. The method first applies a finite impulse response low pass filter to the incoming signal thus increasing the fading power to noise ratio. Applying a root-MUSIC frequency estimation model, a sinusoidal model for the fading process is obtained. This model can be used to enhance the performance of spatial diversity schemes or temporal processing schemes to reduce the effect of the fading.
