Analog-to-Digital Converter Selection for Digital Receiver

摘要

There are computational and empirical approaches to analog-to-digital converter (ADC) selection in digital receiver. Simplified calculation methods are based on the idealized ADC model. These methods take into account only the quantization noise associated with the ADC bits number, sampling frequency, signal-to-noise ratio. The calculation results has estimate character. The structural constraints to the ADC parameters are determined with the receiver realization. They must be considered when ADC choosing. The study of theoretical relationships allows identifying the computational models application area limitations. The performed analysis shows wider correlation of the radio frequency channel parameters and different ADC parameters. It is possible to consider these parameters interrelation from with regard to their effect on the received signal conversion accuracy, and make a ADCs choice based on unified methodological positions.
