Abstract
In this paper, a signal detection scheme using parallel interference cancellation (PIC) joint with successive interference cancellation (SIC) is proposed for an asynchronous cooperative cellular system utilizing the efficient joint distributed space-time coding (J-DSTC). Simulation results demonstrate that the proposed scheme outperforms the conventional J-DSTC equalization scheme in suppressing the interference at the destination upon receiving the jointly encoded transmit signals from the relay user using J-DSTC, including the information of both the relay user and the source user. It is also shown to be effective in removing the impact of inter-symbol-interference caused by the imperfect synchronization during the cooperative transmission. Meanwhile, a low structural and computational complexity is retained.
