Efeito do Desbalanceamento de Clusters no Modelo η-µ

Higher-order statistics for the phase process of a general η-µ fading model is obtained. In particular, such statistics is derived for the case in which imbalance of multipath clusters between in-phase and quadrature signals in the η-µ fading model exists. Exact, closed-form expressions for (i) the joint probability density function of the envelope, phase, and their time derivatives and (ii) the phase crossing rate are obtained. The combined effect of power imbalance as well as multipath clustering imbalance is then explored, both for the envelope and the phase.
