Capacity enhancement and power allocation using a multi-antenna relay system

In this paper, the issue of capacity enhancement and power allocation has been presented using multi-antenna relay system. The multi-antenna relay system is constructed by a selective decode-and-forward (SDF) and an incremental-decode-and-forward (IDF) protocol. These two protocols are jointly introduced in a cooperative relay network. We have derived the issues of outage capacity and power allocation for each protocol and demonstrated that they can outperform high capacity and allocated 90% power. All relay input signals are combined, re-encoded and re-transmitted to the destination. We have proposed the multi-antenna relay with the joint protocol relay system which efficiently enhances the capacity and power allocation of the cooperative networks.
