The practical applications within the domain of the fifth generation (5G) and the emerging beyond 5G network necessitate a high data transmission rate along with minimal achievable delay. With this objective in focus, the maximum capacity is extensively quantified through the utilization of the delay-constrained effective capacity (EC) technique, which stands in contrast to Shannon's ergodic capacity. The current study is engaged in the analysis of EC within a delay-limited wireless system operating in a double-shadowed Rician (DSR) fading channel. Within this channel, only the Nakagami-m distribution concept has been applied to both the dominant and secondary shadowing components of the proposed network model. A new exact closed-form expression for EC within the DSR fading channel has been derived using the Fox-H function. Furthermore, an analysis has been conducted for both high and low signal-to-noise ratios to provide further insights and explanations for the proposed model. It is worth noting that the results obtained from both simulation and analytical methods exhibit substantial similarity, revealing interdependence among various parameters present in the proposed model.

基于Nakagami-m分布的双阴影莱斯衰落信道有效容量性能分析

第五代 (5G) 和新兴的超 5G 网络领域的实际应用需要高数据传输速率和可实现的最小延迟。围绕这一目标，通过利用延迟约束有效容量（EC）技术对最大容量进行了广泛的量化，这与香农的遍历容量形成鲜明对比。当前的研究致力于分析在双阴影莱斯 (DSR) 衰落信道中运行的延迟有限无线系统内的 EC。在此通道内，仅 Nakagamim分布概念已应用于所提出的网络模型的主要和次要阴影组件。使用 Fox-H 函数导出了 DSR 衰落通道内 EC 的新精确封闭式表达式。此外，还对高信噪比和低信噪比进行了分析，以为所提出的模型提供进一步的见解和解释。值得注意的是，模拟和分析方法获得的结果表现出很大的相似性，揭示了所提出模型中存在的各种参数之间的相互依赖性。
