| Popis: | The bivariate double-Rayleigh distribution with non-identically distributed parameters is introduced and analyzed. Novel series expressions for the joint probability density, cumulative distribution, and the moments are derived. Based on this new distribution, a multichannel communication scenario is studied, where correlation exists between the actual channel and its corresponding estimate, under time varying channel assumption. In this context, the outage performance of the system under consideration is analytically evaluated, while for higher values of the average signal-to-noise ratio, closed-form results are derived. Finally, an analysis for total outage probability in varying-correlation conditions is also provided. |
