    Abstract: In our paper, we present the implementation of two kinds of FPGA-based modulators: ASK and QAM signal modulators. The ASK modulators we implemented are OOK, ASK, and 4ASK, then the QAM modulators implemented are 4QAM and 16QAM. The generation of the sine wave carrier is the main task when implementing any digital transmitter including ASK and QAM m... Show More
