data rate, interference cancellation is likely to be required in cooperative
networks at the symbol level to mitigate synchronization
errors. In this paper, we therefore examine closed-loop extended
orthogonal space time block coding (CL EO-STBC) for four relay
nodes and apply parallel interference cancellation (PIC) detection
scheme to mitigate the impact of imperfect synchronization. Simulation
results illustrate that the closed-loop EO-STBC scheme under
imperfect synchronization can achieve good performance with
simple linear processing and outperform previous methods. Moreover,
a PIC scheme is shown to be very effective in mitigating impact
of imperfect synchronization with low structural and computational
complexity.
