Webulus of a Gaussian complex random variable. In the circular case, it is a Log-Rayleigh (LR) variable, whose probability distribution function (pdf) depends on only one parameter. In the noncircular case, the pdf is more complicated, although we show that it can be adequately modeled by an LR pdf, for which the optimal ﬁtting parameter is derived.

WebCircular distributions can be used even when the variables concerned are not explicitly angles: the main consideration is that there is not usually any real distinction between events occurring at the lower or upper end of the range, and the division of the range could notionally be made at any point. Graphical representation [ edit] Circular symmetry of complex random variables is a common assumption used in the field of wireless communication. A typical example of a circular symmetric complex random variable is the complex Gaussian random variable with zero mean and zero pseudo-covariance matrix.
