In telecommunication systems, the transmitted signal experiences several types of impairment within propagation; namely path loss, shadowing, and fading. To reduce the impact of fading, a diversity of combining is required on the receiver side of the wireless system. Among the most efficient combining techniques, the equal gain combining has shown a high performance and easy building in comparison to the remaining ones. In this Letter, we have studied the effective throughput metric to evaluate the performance of equal gain combining technique over correlated Weibull fading channels. The presence of analytical expression of effective throughput has been obtained under both normal and high signal noise-to-ratio regimes. In addition, the effective throughput has been illustrated versus various parameters to show its behavior. The analytical results have been validated using the Monte Carlo simulation technique and the precision of the finding has been proved.
