8.4 STOCHASTIC DIFFERENTIAL EQUATIONS RADIO
COMMUNICATIONS FRAMEWORK
The accurate modeling of radio channel’s time evolution is of high importance in current and future
mobile computing systems. Moreover, the statistical approach of the communication problems is
dominant since real radio signals are not deterministic and have a stochastic nature. Single and
multidimensional long-term probability distributions representing the rst-order statistics are not
sufcient for the accurate radio channel characterization and modeling. The second-order statistics
(such as covariance matrices, ...
