This paper proposes a cooperative space-time coding (STC) protocol, amalgamating the concepts of asynchronous cooperation, non-coherent detection as well as Distributed Turbo Coding (DTC), where neither symbol-level time synchronization nor CSI estimation is required at any of the cooperating nodes, while attaining a high performance even at low SNRs. More specifically, a practical cooperative differential...
The adaptive transmission jointly considering adaptive modulation and coding (AMC) and automatic repeat request (ARQ) has been applied to MIMO systems to provide high spectral efficiency and link robustness. However, the adaptive transmission requires knowledge of the channel state information (CSI) and in practice perfect CSI is rarely available. In this paper, under the condition of finite-length...
