The article is devoted to the study and implementation of Quadrature Amplitude Modulation (QAM) on the Altera DE2-115 debug board. A definition of QAM modulation is given and various types of QAM constellations are mentioned. The principle of operation and the model of the transceiver are considered. The developed model describes the processing processes that take place in the receiver and transmitter. The implementation of 16-QAM in the MATLAB environment is considered, the influence of the choice of the FIR filter on the suppression of the received signal is shown. The model developed in the MATLAB simulation environment is implemented on the Altera development and educational board. The constructed model is tested, its output signals are shown. The implemented SDR allows the exchange of modulated data at a rate of 35 MHz.
