A general statistical model for fast fading channel simulation

A new statistical model for fast fading channel simulation for both line of sight (L.O.S.) and no L.O.S. cases, has been developed using the theory of statistics. Considering that there is a finite number of fixed or randomly moving scatterers in the propagation medium, then in proportion to the central limit theorem the received signal is a modified Student´s process (eq. 1). Thus the amplitude variations of the recived signal (the channel´s impulse response envelope variations), termed as fast fading, can be modelled by the new so called POCA distribution, which can be found by the following analysis.
