Popis:	This article describes an implementation of a discrete frequency demodulator using modified discrete Fourier transform DFT (MDFT) filter banks analysis. To improve noise immunity, a Reed-Solomon decoder was used. The demodulator is implemented on a processor (CPU) with ARM architecture and a graphics core (GPU) Mali. The article compares the performance of filters performed both on the CPU and on the GPU, with a different number of channels.
