Short-term Fluctuations

Following (1) each component tex2html_wrap_inline1009 can be written as a sum of numerous plane waves with random characteristics. In the SRCM the amplitude, delay and incidence direction are randomly chosen in such a way that the resulting PDDP is close to tex2html_wrap_inline1011 . As already mentioned the short-term fluctuations of the FDDSF origin exclusively in the phase changes that appear during the MT antenna movement along the trajectory.
