In this manner, digital modulators’ that are able to process 8-, 16-, and 64-quadrature amplitude, are realised herein by using embedded systems like the well-known field-programmable gate array (FPGA). It is worth mentioning that using FPGAs allows us to perform a reduction of the hardware resources. This issue also allows relaxing the operating conditions of the systems in the digital domain. Several experiments are shown to demonstrate the usefulness of an FPGA, like using Stratix III DSP Development Kit, and to confirm the good agreement of the experimental results with theoretical ones.
