Abstract :
This paper presents system design aspects of a multi-relay half-duplex QMF cooperative system. We propose two simple algorithms that address the design of relay scheduling and inter-relay interference schemes. Proposed linear-complexity scheduling algorithm is proven to be optimal for a multi-relay diamond network under specific channel conditions. We demonstrate through simulations that for typical channel conditions, the achievable QMF rate of a five-relay cooperative system is up to 3 times higher compared to a system without cooperation.
