An Asymptotic Framework for Fox's H-Fading Channel With Application to Diversity-Combining Receivers
Publikováno v:
IEEE Open Journal of Vehicular Technology, Vol 4, Pp 404-416 (2023)
Unified statistics are valuable in the performance analysis of communication systems. In this context, Fox's H-function has been shown to be eminently suitable for diverse scenarios. Another pivotal requirement is to have a low computational complexi
