Abstract

In this paper, a sub-optimum detection scheme is proposed for distributed closed-loop quasi orthogonal space time block (D-CL QO-STBC) for two dual antenna relay nodes in decode-and-forward (DF) asynchronous cooperative relay network. The direct transmission (DT) link connection among the source node and the destination node is considered in this network. The proposed scheme is robust against synchronization error and it reduces the receiver complexity as compared to previous work. Furthermore, the maximum available cooperative diversity gain and full transmission rate between the relay nodes and the destination node, and symbol-by-symbol decoding are all achieved. Simulation results are demonstrated to show the proposed scheme for various synchronization errors and effectively eliminate the interference components induced by intersymbol interference (ISI) among the relay nodes.

Notes

  1. 1.

    The received signal becomes practically uncorrelated, if the antennas at the relay nodes are spaced equal to half of transmitted wavelength signals.
