Outage probability of AF CDMA hybrid satellite-terrestrial cooperative networks using multiple relays over shadowed-rician fading channels

摘要

The outage probability analysis of amplify-and-forward (AF) cooperative code-division multiple-access (CDMA) systems is presented over independent non identical (i. n. i.) Shadowed-Rician fading between Satellite-Relay and Satellite-Destination link; and Nakagami-m fading channel between Relay-Destination link. Multiple transmission cooperative protocols are investigated. The total signal-to-noise ratio (SNR) was used to derive the moment-generating-function (MGF) in closed-form expression for hybrid satellite terrestrial cooperative Networks (HSTCNs). The outage probability is acquired using the MGF derived for the proposed system. Analytical outage probability results are verified through comparison with Monte Carlo simulations. The results also show that utilizing cooperative relay communication systems will intensely increase the performance, as well as exploiting CDMA systems.
