Implementation of a Multi-Channel Demodulator of Discrete-Frequency Signals Using DDC on a GPU

The article is devoted to the implementation of a multi-channel demodulator of discrete-frequency signals using modern technologies. The main stages of the process of demodulation of signals of this type are considered. It is proposed to use DDC to filter partial channels. Hardware implementation options on DSP and FPGA, ARM and GPU, CPU (personal computer and server) and GPU are analyzed. As a result, estimates of the number of realized channels on a certain hardware platform in multichannel communication systems are obtained. The prospects for using the implementation of algorithms on the GPU are shown.
