Non-linear filtering of pulse signals in case of high intensity noise
Signal standing out from the high-intensity noise is a main task in diagnostics of power beam plasma systems. Pulse signals detection from wide-band noise under low value of the signal-to-noise ratio is considered. Stochastic resonance effect as a method of investigation scrutinized. The algorithm a...

| Summary: | Signal standing out from the high-intensity noise is a main task in diagnostics of power beam plasma systems. Pulse signals detection from wide-band noise under low value of the signal-to-noise ratio is considered. Stochastic resonance effect as a method of investigation scrutinized. The algorithm and program for the numerical solution are developed. The comparative analysis of ranges of the useful signal on an output of stochastic and linear filters is carried out. Estimates of quality of filtering in case of pulse width modulation signals are calculated. Criteria of nonlinear filtering of pulse signals in case of high intensity noise are formulated. |
