Abstract

In this paper distributed space time codes (D-STBCs) are applied within an asynchronous cooperative wireless relay network to achieve significant performance gain for the case of two relay nodes. Since interference at symbol level is an issue that reduces the performance gain in cooperative relay networks, a parallel interference cancellation (PIC) detection scheme at the destination node is applied to overcome the impact of imperfect synchronization among the cooperative relay nodes. Our end-to-end coded bit error simulation results show that the PIC detection algorithm can mitigate the inter symbol interference (ISI) greatly, and a small number of iterations is necessary within the PIC detection to improve the system performance, with low structural and computational complexity.
