Abstract :
Principles, advantages, limitations and hardware requirements for implementation of the discrete nonlinear EMC system analysis (DNA-EMC) are described. DNA EMC implies application of discrete models of the electromagnetic environment and of accumulative signal in radio receivers, high order polynomial models of nonlinear transfer characteristics, polychotomous identification procedures for interference sources; Hilbert transform to extract signal envelope when modeling the amplitude-phase conversion and detection processes and digital signal processing to analyze signal distortion during its reception in severe electromagnetic environment.
