Abstract:
The paper offers a way of solving the problem of electromagnetic compatibility of radioelectronic facilities operating simultaneously on a co-frequency basis by using digital filters that preserve the input signal amplitude and waveform. The possibility and potential efficiency of cancellation of pseudo-random sequence encoded phase shift keying radio interference signals, forming methods of which are known to authorized users, by using digital filters that preserve the input signal amplitude and waveform, resulting in simplification of design and technical implementation and increase in operational reliability of radio interference canceller hardware due to rejection of the necessity of using analog and analog-to-digital closed-loop servo systems have been demonstrated.
