Title
Outage capacity evaluation of extended generalized-K fading channel in the presence of random blockage
Abstract
In this paper, we analyse the outage and ergodic capacity performance of the extended generalized-K fading channel in the presence of possible temporary physical blockage between the source and the destination. Presented outage capacity analysis is general and can be used in analysis of wireless radio frequency or free-space optics systems. We establish the novel relation among significant parameters as outage capacity, probability of outage, probability of blockage, as well as severity and shaping parameters of multipath fading and shadowing. The theoretical results are expressed in terms of special Fox׳s H functions. The work clearly illustrates the usefulness of Fox׳s H and Meijer׳s G functions in analysing wireless communication systems. The analytical expression derived here enables us to determine the maximum error free data transmission rate for fixed value of outage probability under particular channel conditions. Using expressions for ergodic capacity previously reported in literature, we briefly analyse the impact of blockage on ergodic capacity, too. The numerical results show that the shadowing shaping factor has the considerable effect on outage capacity and is pronounced more extensively when probability of outage is lower. In addition, the results show that the effect of shadowing shaping factor is stronger for outage than ergodic capacity. The effect of multipath fading severity on outage capacity is stronger for lower values of shadowing spread. The link blockage causes significant decreasing of ergodic capacity and appearance of outage floor.
