An iterative layered interference canceller scheme for OFDM in wireless mesh security networks

摘要

The wireless mesh security networks (WMSN) are widely used in next generation communications due to their coverage and convenient deployment. However, when radio nodes communicate with each other simultaneously in a single network, interference may occur, leading to no recoverability of some signals. Moreover, the interference has a bad influence on the network security. To solve this problem, we introduce a novel layered interference cancellation scheme (LIC). Through computer simulations, we demonstrate that the proposed system achieves good error performance and provides effective and flexible interference cancellation in WMSNs.
