Research Noise Immunity of Message Reception in Radio Engineering Systems

Methods for improving the noise immunity of useful traffic message reception in radio engineering systems are analyzed. Based on this research, a new approach to constructing a mathematical model for assessing the noise immunity characteristics coherent modem reception in radio engineering systems operating under conditions of unintentional interference sources is proposed. The developed mathematical model takes into account the operating algorithm of the radio engineering system detector synthesis, decoding methods, and efficient modulation and coding methods. It is proposed to use the probability correct reception of a code message in radio communication as an indicator of noise immunity. Important analytical expressions are derived for assessing the noise immunity characteristics message reception, taking into account the receiver's spectral parameters.
