  3. Abstract • The performance of average level crossing rate (LCR) and average fade duration (AFD) of the output signal of the maximum ratio combining (MRC) and the selection combining (SC) with a dual-branch receiver was analyzed. • The channel model of the diversity branches are assumed characterized as correlated Nakagami-m statistics. • The numerical analysis is conducted for verification.

  4. Introduction • The MRC and SC diversity techniques. • The correlated Nakagami-m fading Channels. • The evaluation methods of LCR and AFD.

  21. 5. Conclusions • The average LCR and AFD are evaluated in this paper for MRC and SC work with dual correlated Nakagami-m fading channels. • The small value of branch is assumed in the paper, but the existing performance degradation is fixed. • The results from the numerical analysis indicate that average LCR and AFD are significantly affected by the correlation between branches with MRC and SC schemes, that is, the fact of correlation characteristic of branches is not negligible in designing the wireless radio systems. • In future, in order to make the results are confident, some of the detail simulations will be held.
