Implementation of M-CpFSK Signal Reception Using ARM Processor with GPU and SDR Receiver

The article is devoted to the possibility of implementing a receiver of multi-frequency Cp-FSK signals. To obtain a stream of digital samples, the use of a software-defined radio (SDR receiver) is considered. For demodulation, it is proposed to use single-board PCs with ARM architecture processors and graphic processors. The use of GPUs allows the use of computationally efficient digital filter bank algorithms to receive multi-frequency Cp-FSKs. The article considers the implementation of the reception of a signal-code structure based on multi-frequency signals and non-binary error-correcting codes. The proposed device can be used for UAV command telemetry radio links.
