Abstract :
The paper studied the outage performance for MIMO Multi-Relay ISDF (MR-ISDF) (Incremental and Selective Decode-and-Forward) cooperative communication systems. Firstly, the end-to-end mutual information, outage and OPA (optimal power allocation) for MR-ISDF was derived under the technology of MRC and beam-forming. Then the optimal single ISDF (OS-ISDF) which acted as routing protocol was introduced. Thirdly, we analyzed the close form end-to-end mutual information and outage for OS-ISDF systems and proved that outage for OS-ISDF is the low bound for MR-ISDF. At the end, simulation verified the theory analyses. In addition, outage for OPA scheme outperforms that for EPA (equal power allocation). At 10-6, outage for OPA scheme has 2dB gain than that for EPA.
