Abstract :
In this paper, a new signal detection scheme using both parallel interference cancellation (PIC) and equalization for the efficient joint distributed space-time coding is proposed to suppress the impact of imperfect synchronisation in distributed cellular systems. Simulation results show that the proposed scheme outperforms the existing joint DSTBC decoded scheme in terms of BER. And also it achieves the same system capacity as the existing scheme. Meanwhile, a low structure and computational complexity has been retained.
