Abstract :
Wireless MIMO relay networks are receiving significant interests in recent years. However, most of MIMO relay techniques require high complexity equalizers and error free forwarding at the relay to collect diversity. In this paper, we propose high-rate and low-complexity MIMO relay designs that achieve joint cooperative and receive diversity by adopting power scaling strategy at the relay and channel-controlled (CC-) ARQ techniques. Linear equalizers are employed at both the relay and the destination to maintain low-complexity. Through mathematical analysis, we prove the diversity order achieved by proposed design. The theoretical analysis is corroborated with numerical simulations.
