This paper presents the implementation algorithms for quadrature modulator and demodulator 16 qAM as SDR functions on programmable logic devices, particularly for FPGA platforms. It presents all the model analysis, design and implementation of it, and considering the results of implantation of the device as a component of a cognitive satellite transponder. The validation process of the implementation was done through the design tools, simulation, synthesis, and downloads on Xilinx Spartan 3E FPGA.
