Abstract:

The work is concerned with the development and application of an analytical model for atmospheric noise, which is radio noise originating in lightning discharges. The generalized t model resulting from our approach is in good agreement with measured data and describes the received atmospheric noise yt as yt at nt, where nt is a narrowband gaussian process and at is a slowly varying random process, independent of nt, that modulates nt. The detection of known signals in additive generalized t noise is considered, and the receiver that minimizes the probability of error found to be a nonlinear logarithmic-correlator receiver. Analytical and experimental results indicate that the probability of error achieved by this receiver in the presence of additive atmospheric noise.
