Power Constrained Channel Capacity over Generalized Composite Fading Conditions

This contribution addresses the channel capacity of digital communications over shadowed generalized multipath fading environments. This is realized in the context of κ – μ shadowed channels for the case of optimum rate adaptation and optimum power and rate adaptation. Based on this, novel analytic expressions are derived for the above performance measures, which are subsequently utilized in the evaluation of the incurred generalized multipath fading and shadowing phenomena in different practical scenarios of interest. This allows the development of insights that can be useful in the realistic design of emerging wireless set ups as it is shown that the severity of composite fading is significant also in the context of channel capacity since variations of over 20% are observed in different severity levels.
