Executive Summary

This paper focuses on comparing performances of the Selection Combining (SC) diversity system in the presence of independent and correlated Ricean fading. For the case of correlated fading, the authors have presented closed form expressions for Probability Density Function (PDF), and Cumulative Density Function (CDF), at the output of dual branch SC. Also they have presented closed form expressions for system performances such as: Average Bit Error-Rate (ABER), Outage Probability (OP) and average output moments, which is the main contribution of their work. For the case of independent fading between the diversity branches, they have analyzed performances of SC diversity system which consists of two and four input branches.
