Effective Rate Analysis in Weibull Fading Channels

Recently, the theory of effective rate has attracted much attention, since it can take the delay aspect into account when performing channel capacity analysis. Weibull fading model is a flexible and practical model for describing fading channels in both indoor and outdoor environments. This letter derives the exact analytical expressions of effective rate over independent but not necessarily identical Weibull fading channels, which can be used in the system analysis in real-time communication scenarios. In addition, the closed-form asymptotic expressions under high signal-to-noise ratio (SNR) and low-SNR regimes are derived to provide useful insights into the effects of system and fading parameters on the effective rate.
