Abstract:

Due to the broadcasting nature of wireless transmission, the cochannel interference in heterogeneous networks among the cells can be a potential limiting factor in cellular systems. To overcome this limitation, many interference mitigation techniques for femto-cells have been proposed, which mainly focus on power control and spectrum allocation. In this paper, through the technique of dirty-paper coding, we are motivated to develop an interference cancellation (IC) method that operate independently in each femto-cell. It is worth to mention that the proposed method can be implemented without further feedback information between macro-cell and femto-cells. Such less coordinated feature of the proposed solution is critical in 3GPP scenarios since it has been aligned that there is no backhaul coordinations among macro-cell and femto-cells in Rel-10 baseline solutions. The simulations show that the proposed method can further reduce the bit error rate (BER) and increase the throughput. Both the significant performance improvements and backward compatibility implies the proposed method has immediate potential in 3GPP systems.
