Power Efficient Cooperative Relay Systems for Multiuser MIMO

Soobum Cho, Sang Kyu Park, and Dong Geol Ryu

Abstract—This paper introduces a power efficient cooperative relay system with several antennas to achieve precoding gain and distinguish multiuser with one antenna. In a common relay transmission, the performance of decode-and forward (DF) protocol is decreased when it uses higher modulation scheme. The proposed scheme not only increases a transmission data rate as one more bit per frame, but also reduces the maximum relay power consumption by a cooperative grouped relay scheme.

Index Terms—Cooperative relay, precoding gain, decode and-forward (DF), power consumption
