Methods and Means of Ensuring Stability and Protection of Radio Communications in a Complex Electromagnetic Environment

The article contains a review of a wide range of methods and means to ensure the stability of communication and protection of radio transmissions, including encryption, frequency hopping, the use of directional antennas, masking, and interference-resistant coding.

The method and simulation model for the synthesis of barker-like code sequences

Noise immunity is one of the essential characteristics of modern wireless data reception/transmission systems. In wireless systems such as Wi-Fi, HiperLan, or Bluetooth, the signal is propagated by electromagnetic oscillations in the environment. However, unlike wiring systems, these oscillations are unprotected from external influences.
