OUTAGE PROBABILITY ANALYSIS OF SELECTIVE-DECODE AND FORWARD COOPERATIVE WIRELESS NETWORK

    Spatial diversity is the main advantages of MIMO systems. Despite the advantages, antenna diversity may not be practical for many wireless scenarios due to hardware limitations, cost, and size of the equipment. Also, non-cooperative transmission is very expensive due to high transmit power necessary for the reliability of the wireless system. In this design, the outage probability (OP) analysis of selective decode and forward (SDF) cooperation protocol employing multiple-input multiple outputs (MIMO) orthogonal space-time block-code (OSTBC) over time-varying Rayleigh fading channel conditions with imperfect channel state information (CSI) and mobile nodes are analyzed. The closed-form expressions of the per-block average OP, probability distribution function (PDF) of the sum of independent and identically distributed. Gamma random variables (RVs), and cumulative distribution function (CDF) are derived and used to investigate the performance of the relaying network. Matlab simulation results show that the equal power allocation is possible for an optimal solution when source to relay link is stronger than the relay to destination link.
