On the Condition for STBC Cooperative System Outperforms Direct System
Lijian Ding, Q. YIN, Yujun Zhang, Yifei Meng · IEICE Transactions on Communications · 2007
This letter investigates a practical space time block coded (STBC) cooperative system to determine under what conditions a cooperative system outperforms a direct one, and then proposes two criteria for selecting proper relay based on outage probability and capacity, respectively. Performance analysis and numerical results indicate that the STBC cooperative system is superior in practical scenarios.
