New Approximate Expressions for αημ and ακμ Fading Channels Subjected to Inverse Gaussian Shadowing With Applications

Abstract

In this paper, new approximate expressions of probability density functions, tth-moments and moment generating functions of the instantaneous SNR for αημ and ακμ fading channels subjected to Inverse Gaussian shadowing have been derived. The obtained statistics have been applied to ascertain Amount of Fading (AoF), channel capacity per unit bandwidth, and Average Symbol Error Rate (ASER). The performance of these matrices has been studied under various channel parameters. To judge the performance of multi-hop communication, Source to Sink Average Bit Error Rate (S2S-ABER) has been calculated for two individual cases: (i) independent and identical distributed and (ii) independent and non-identical distributed multi-hop links. Moreover, the performance of multi-hop IEEE 802.15.4 Zigbee and IEEE 802.15.1 Bluetooth radios have also been analyzed over these channels. Simulations have been performed to validate the derived expressions.
