In this paper distributedspacetimeblock codes (D-STBCs) are applied within an asynchronous two-way cooperative wireless relay network using two relay nodes. A parallelinterferencecancelation (PIC) detection scheme with low structural and computational complexity is applied at the terminal nodes in order to overcome the effect of imperfect synchronization among the cooperative relay nodes. Simulation results based on end-to-end bit error rate (BER) illustrate that the PIC detection algorithm can mitigate the inter symbol interference (ISI) introduced by the asynchronism, and that only a small number of iterations is necessary within the PIC detection to improve the system performance.
