Asynchronous Cooperative MIMO Systems Using a Linear Dispersion Structure

In this treatise, we propose a novel family of asynchronous cooperative linear dispersion codes (ACLDCs), which is capable of maintaining full diversity in cooperative scenarios, even in the presence of asynchronous reception. The linear dispersion structure is employed to accommodate the dynamic topology of cooperative networks, as well as to achieve higher throughput than conventional space-time codes based on orthogonal designs. By introducing guard intervals and block encoding/decoding techniques, the interference signals caused by asynchronous reception can be exploited rather than discarded.
