Average Fade Duration

Exact and closed form expressions for the average level crossing rate (LCR) and average fade duration (AFD) of the output signal envelope of selection diversity system are derived, assuming each branch is subject to independent but nonidentical composite fading in distributed antenna systems (DAS). Numerical results validate the derived expressions. It shows that DAS promise significant diversity gains over collocated multiple antenna system.

In this paper,the wireless communication system with dual SC receiver operating over shadowed multipath fading channel is considered. The multipath fadingis k-μor Rician.The received signal experiences the short term fading which is resulting in SC receiver envelope variation and Gamma long term fading resulting in SC receiver envelope power variation. The closed form expressions for joint probability density functions of SC receiver output signal envelope and their first derivative of SC receiver output signal envelope are calculated for both, k-μand Rician fading. These expressions are used for evaluation of average level crossing rate of SC receiver output signal envelopes. The numerical expressions are plotted to show the effect of Rician fading severity parameter and Gamma shadowing severity parameter on the average level crossing rate of SC receiver output signal envelope.
