INVESTIGATION OF THE INFLUENCE OF THE PEAK FACTOR OF INPUT SIGNALS ON SOME CHARACTERISTICS OF THE ADC

This article evaluates the effect of the peak factor of input signals on the signal-to-noise ratio of an analogto-digital converter (ADC). It is indicated that ADC play an important role in modern radio communication systems based on software-configurable radio systems. It is noted that one of the key characteristics of the ADC is quantization noise, which directly affects its important property such as the signal-to-noise ratio. An expression is described for calculating the signal-to-noise ratio of the ADC, depending on the peak factor of the input signal. The evaluation of the signal-to-noise ratio of the ADC for radio communication systems with various types of signals (simple signals; signals generated using binary pseudorandom sequences; signals generated using chaotic signal generators) was carried out. The results obtained, taking into account the assumptions and limitations introduced, show that the peak factor of input signals directly affects the signal-to-noise ratio of the ADC, and its influence should be taken into account when operating, developing and improving modern radio communication systems, including those using promising complex signals.
