On the Performance Analysis of Cognitive Radio Based Wireless System Over Weibull-Inverse Gamma Composite Fading Channel

An approximate statistical analysis of wireless channel over α − μ shadowed fading channel

“…As we know estimation of wireless channel while considering delay is an essential part for various real time applications. This metric is called link layer analysis, commonly known as Effective capacity 29–34 . Further, the same metrics are developed in high‐ and low‐power regimes over κ − μ and η − μ shadowed environment 29 .…”

“…This metric is called link layer analysis, commonly known as Effective capacity. [29][30][31][32][33][34] Further, the same metrics are developed in high-and low-power regimes over κ À μ and η À μ shadowed environment. 29 The concept of secrecy in multicast transmission under the presence of multiple eavesdroppers over η À μ/I-Gamma composite fading is explored in Hanif et al 30 In Maurya et al, 31 the analytical framework of energy detection in α À μ/I-Gamma fading channel for single-input-single-output (SISO) and single-input-multiple-output (SIMO) is discussed.…”

“…29 The concept of secrecy in multicast transmission under the presence of multiple eavesdroppers over η À μ/I-Gamma composite fading is explored in Hanif et al 30 In Maurya et al, 31 the analytical framework of energy detection in α À μ/I-Gamma fading channel for single-input-single-output (SISO) and single-input-multiple-output (SIMO) is discussed. Additionally, the energy detection metrics such as probability of detection and area under receiver operating characteristic are derived for the generalized case of α À μ/I-Gamma (Weibull/I-Gamma) in Upaddhyay et al 32 Upaddhyay et al 33 developed an exact closed-form probability density function (PDF) in terms of Mellin-Barnes integral and average SEP expression in complex bivariate Fox's H-function over α À μ/I-Gamma fading channel, which makes direct interpretation of fading parameters intricate. Generally, delay at the buffer is characterized through link layer metric termed as effective capacity (EC).…”

Analytical framework for the performance of energy detectors over α‐μ fading model with MRC diversity

“…Various combining algorithms are exercised in this method to administer the output from these antennas, such as the selection combining (SC), equal gain combining (EGC), generalized selection combining (GSC) and maximal ratio combining (MRC) algorithm. 14,15 In the past, various authors have acknowledged the study of the ED-based CR devices in their works like, Sofotasios et al 16 presented the performance analysis of spectrum sensing with ED over the Weibull fading model, while in Upaddhyay et al, 17 the analysis is extended to consider more realistic composite Weibull/Inverse-Gamma fading distribution. Verma et al 18 carried out analysis over the inverse-Gaussian fading model with SC diversity, whereas in Maurya et al, 19 the inverse-gamma fading model is employed to study the performance of ED with SC and MRC diversity.…”
