Transformation of phase-shifted signals by filters of selective suppression of narrow-band interference and masking pseudo-random signals of the Lorentz system
Modeling and investigation of filters of selective rejection of narrow-band noise with a priori unknown frequency and selective suppression of multidimensional pseudorandom signals of discrete-nonlinear Lorentz system are carried out. The transformation of signal with phase manipulation in the digital selective nonlinear reject filter are studied. The digital functional rejection filters for selective signal rejection by form, synthesized in according to the principle of two-channel invariance theory, in information transmission systems with PSK-signals for suppressing additive harmonic signals of narrowband interference and masking pseudo-random signals of discrete nonlinear Lorentz systems is recommended. Recommendations on the use of digital non-linear rejection filters using mathematical programs are developed and justified.
