Abstract

This paper proposes a new distributed space-time block code (DSTBC) over frequency selective fading channels in amplify-and-forward (AF) turbo-coded cooperative wireless relay networks with hybrid automatic repeat request (HARQ) combining schemes. The proposed DSTBC and HARQ schemes are designed to achieve spatial diversity gain and low decoding complexity. These goals are obtained by precoding the received signal at the relay to form the conventional space-time block codes. In addition, the coding gain is combined with the diversity gain to enhance the performance of DSTBC by adding turbo coding at the source and iterative decoding at the destination. Together with turbo coding, two fundamental HARQ combining schemes are considered in our design, including Chase combining (CC) and incremental redundancy (IR).
