Abstract:

The work develops the mathematical model of a radio receiver operating in an interference environment. Amplitude and frequency modulation are treated. Linear and non-linear effect on the field ensemble are considered. The underlying criterion used in the model is the signal-to-noise power ratio after detection. This ratio is shown to have a frequency distribution that is a function of the distribution of the attenuations of the signals contributing to it. The probability of interference is shown to be a function of the difference between the values of the distribution functions of the ratios with and without interference for the value of signal-to-noise ratio required of the circuit.
