Abstract
In this paper, we propose an efficient distributed closed-loop QOSTBC with Parallel Interference Cancellation (PIC) Detector under Quasi-Synchronization in the case of four relay nodes with SDF protocol. After mitigating the impact of imperfect synchronization by PIC method, we combine the received signals of DT link between the source node and the destination node during the first phase with the closed-loop QOSTBC signals from the relay nodes during the second phase. Comparing with the traditional schemes which do not considering the DT link signals, our scheme can improve the SER performance significantly in all SNR region. Furthermore, Comparing with the perfect synchronization system, our scheme can achieve almost the same SER performance in the lower SNR region.
