On the Effective throughput of Shadowed Beaulieu-Xie fading channel

Given the imperative for advanced wireless networks in the next generation and the rise of real-time applications within wireless communication, there is a notable focus on investigating data rate performance across various fading scenarios. This research delved into analyzing the effective throughput of the shadowed Beaulieu-Xie (SBX) composite fading channel using the PDF-based approach. To get the simplified relationship between the performance parameter and channel parameters, the low-SNR and the high-SNR approximation of the effective rate are also provided. The proposed formulations are evaluated for different values of system parameters to study their impact on the effective throughput. Also, the impact of the delay parameter on the EC is investigated. Monte-Carlo simulations are used to verify the facticity of the deduced equations.Comment: 18 page

Statistical Relation of CMEs Related Geomagnetic Storms With Interplanetary Magnetic Fields

We have studied geomagnetic storm (Dst?-150 nT), associated with Coronal Mass Ejections (CMEs), observed during the period of 2000-2011 with Interplanetary Magnetic Fields. It is observed that coronal mass ejections (CMEs) related geomagnetic storms are found to be association rates of halo and partial halo CMEs  are 18(90%) and 02(10%) respectively. From the further analysis, positive co-relation has been found between magnitude of CMEs related geomagnetic storms and speed of coronal mass ejections (CMEs), with correlation coefficient 0.50. Positive co-relation has been found between magnitude of CMEs related geomagnetic storms and magnitude of change in interplanetary magnetic fields, with correlation coefficient 0.55, positive co-relation has been found between magnitude of CMEs related geomagnetic storms and peak value of change in interplanetary magnetic fields, with correlation coefficient 0.56.

Long-term Modulation of Cosmic Ray Intensity in Statistical Relation with Coronal Mass Ejections and Solar Flare Index Parameters

We have studied statistically correlative analysis of long-term modulation of cosmic ray intensity (CRI) with coronal mass ejections and solar flare index for the period of 1997 to 2010 (23rd and 24th solar cycle). Inverse correlation has been found between solar activity parameters cosmic ray intensity (CRI), coronal mass ejections, solar flare index. Negative correlation with correlation coefficient -0.83 has been found between cosmic ray intensity and coronal mass ejections. Negative correlation with correlation coefficient -0.70 has been found between cosmic ray intensity and solar flare index number. Keywords: Cosmic Ray Intensity, Coronal Mass Ejections and Solar Flare Index

An asymptotic framework for Fox’s H-fading channel with application to diversity-combining receivers

Unified statistics are valuable in the performance analysis of communication systems. In this context, Fox’s Hfunction has been shown to be eminently suitable for diverse scenarios. Another pivotal requirement is to have a low computational complexity, which is often hard to achieve for generalized models. Given this motivation, in this article we have presented high-power, low-complexity solutions for the outage probability (OP) and the average symbol error probability (SEP). Additionally, diversity techniques are harnessed for mitigating the effect of fading, which are then analysed based on the results derived. The entire methodology is governed by the origin probability density function rather than approximating the performance metrics under high-power. All the presented mathematical expressions are compared and validated through computer simulations (Monte-Carlo) to verify the accuracy of the proposed framework
