BER Analysis Over \(\alpha\)-\(\eta\)-\(\mu\)/I-Gamma Fading Channel with Laplacian Noise

In this work, the detailed investigation of the bit error rate (BER) over the \(\alpha\) $\alpha$ - \(\eta\) $\eta$ - \(\mu\) $\mu$ /Inverse-Gamma composite fading channel is performed.The analysis aimed to explore the error rate characteristics over this channel under the influence of additive Laplacian noise. The findings are presented in the form of a bivariate Fox’s H-function, providing a comprehensive representation of the results. Furthermore, the concise and simplified asymptotic expressions of the proposed metrics are provided, enhancing the accessibility and applicability of the results. It is observe that under conditions of high signal-to-noise ratio (SNR), these simplified statistics demonstrate a remarkable level of agreement with the closed-form results. To validate the robustness and accuracy of the proposed formulations, extensive Monte Carlo simulations are conducted to ensure the reliability and validity of our findings across various scenarios and conditions.
