Outage Probability Analysis and Adaptive Power Allocation for ISDF MIMO Cooperation Systems
The outage probability performance is analyzed for the optimization of incremental selection decode-amplify-forward (ISDF) multi-node MIMO cooperative communication systems. Firstly, the system model for the proposed multi-node MIMO cooperative protocol. Then, the incremental selection decode-amplify-forward and optimal relay selection strategy (routing) based on the opportunistic relaying scheme is proposed. The mutual information and outage probability between source and destination nodes for the proposed scheme are formulated with the relays have the capability of maximum ratio combining (MRC) receiving and beam-forming transmitting capabilities. Finally, adaptive strategy is proposed for adaptive optimal power allocation (APA). Theoretical analysis and simulation results show that the proposed APA outperforms traditional equal power allocation (EPA) in outage performance.
