A model for ELF impulsive noise environments is described in detail and some of its properties discussed. A useful and intuitively satisfying model for impulsive noise processes typical of the ELF environment has been shown to consist of the sum of a low-density shot process and white Gaussian noise (WGN). Attention is then directed toward the performance of selected linear and nonlinear receivers operating in noise environments as described by this model. Approximate expressions are determined for the error probability performance of linear matched filter reception binary antipodal signals. These results are extremely useful in providing qualitative insight into the manner in which error probability depends upon the various parameters of the underlying noise model. Simulation results are presented indicating the error probability performance of a number of selected nonlinear receiver structures useful in combating the effects of impulse noise. Finally optimum zero memory nonlinear (ZMNL) receiver characteristics are determined and illustrations are presented to indicate behavior as a function of noise model parameters.
