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. WebMay 9, 2024 · 1. Illustration with damped complex random walks Let ( Zk) be an infinite sequence of identically and independently distributed random variables, with P ( Zk = 1) = P ( Zk = -1) = 1/2. We define the damped sequence as The originality here is that s = σ + it is a complex number.
