Abstract

In this paper, we select the best two relays from a set of available relays, each of which is equipped with two antennas, based on the instantaneous path gains. Closedloopquasi orthogonal space time block coding is then applied over the selected two relays to maximize cooperative diversity. parallel interference cancellation detection is also applied at the destination node to mitigate the problem of imperfect synchronization between the relay nodes. End-to-end bit errorrate simulations confirm that the selection scheme yields a significant improvement in performance over the conventional scheme without using relay selection. Furthermore, the biterror rate simulations confirm the advantages of the detection scheme for a range of levels of asynchronism, and that onlya small number of iterations is required in the parallel interference cancellation technique. © 2012 IEEE.
