Abstract In this paper a modification approach to the range of influence for information potentials (IP)of blind decision feedback equalizer (DFE) algorithms is presented to cope better with impulsive noise and severe channel distortion. Analysis of the IP range of influence reveals that the range should be applied separately based on the roles under impulsive noise. A new cost function that can manage ranges of information potentials is proposed, and a related DFE algorithm is derived. Simulation results from the environment of a severe multipath channel obtained from shallow-water communication experiments and impulsive noise show that the proposed DFE algorithm yields more than 10 dB in MSE gain by employing the proposed modification toranges of information potentials.
