Abstract
Conference Title: 2015 Wireless Telecommunications Symposium (WTS) Conference Start Date: 2015, April 15 Conference End Date: 2015, April 17 Conference Location: New York City, NY, USA In current cooperative communication systems, a relay terminal is very often used as an intermediate node. Introducing this node may degrade or improve the overall system performance, depending on the power imbalance between the hops. In this paper a unified framework to estimate the performance of dual-hop fixed-gain relay system when each hop is subjected to κ-μ shadowed fading is presented. Specifically, new closed form expressions are derived for the outage probability, the generalized moments, the moment generating function (MGF), and the ergodic capacity. This unified analytical framework is obtained in terms of well-known and easily computable functions. The accuracy of the analytical results is verified through computer simulations.
