The Coexistence Between Broadband Power Line Communication and Shortwave Radio Systems with an Optimized Power Allocation Strategy

In this paper, the spectral coexistence between the broadband power line communication system and the short wave radio system is analyzed. The variances of interference signals of each system over the other are obtained firstly, where the significant differences between the two networks are taken into consideration. And then, the global spectral efficiency of the two systems are derived under both uniform and non-uniform scenarios of power allocation among overlapped and non overlapped frequency spectrum. Moreover, some analytical and numerical evaluations of the global spectral efficiency effected by overlapped ratio and power allocation ratio are drawn to verify the proposed power allocation strategy.
