Decision Directed Multiple-Relay Diversity Detector in Asynchronous Cooperative Communication Systems

In this paper, decision directed spatial diversity combining algorithm is presented for asynchronous cooperative communication systems with amply-and-forward relays in frequency flat fading channels. Cyclic prefix assisted single carrier transmission combined with joint frequency domain equalization is carried out to obtain the initial detection solution. Based on that, spatial diversity is employed to improve the performance, where every relayed component in the received signal is decoupled using linear interference cancellation technique, and then the components are synchronized and combined together, so the diversities supplied by the asynchronous relays are acquired. Numerical simulations show the effectiveness of the proposed algorithm.
