Abstract

In this paper, we first derive the approximate symbol-error-rate (SER) for multi-node dual-hop cooperative relay network employing decode-and-forward (DF) protocol with a maximum ratio combining (MRC) at the destination terminal over generalized Nakagami-q (Hoyt) fading channels at high signal to noise ratio (SNR) using the moment generating function (MGF) approach. Using this approximated SER expression, optimal power allocation (OPA) scheme under different Hoyt parameters (q_ij) is developed and investigated. Finally, simulation results are presented to illustrate the performance improvement and power savings due to OPA in the considered cooperative system.
