Application Of An Analog-to-Information Converter In Multichannel Radio Systems

The development of multichannel radio systems leads to a significant increase in data flows that must be transferred from analog-to-digital converters to a computing device. The maximum sampling rate of today's ADCs on the market limits the maximum bandwidth of the signals that can be sampled by the receivers of multichannel radio systems, which does not allow such systems to achieve good resolution. Also, the number of samples that can be obtained at very high sampling rates raises a serious memory capacity issue and increases the processing power required for the digital processing units. One of the approaches that allows solving this problem is the use of analog-to-information converters, which allow performing the compression operation in the process of signal digitization and overcoming the requirement of the Nyquist Rate. In this article, the existing methods for constructing analog-to-information converters are considered, modeling of known algorithms is carried out, and an approach is proposed for creating an analog-information converter in multichannel radio engineering systems.
