Software-Defined Radio uses digital techniques to replace traditional radio hardware such as mixers, modulators, demodulators, and related analog circuits. The result is a flexible radio that can be quickly reconfigured. In this article, a complete radio communication system, that is, the transmitter-receiver, is developed and emulated using Software-Defined Radio. To achieve this, the DSSS technique and the Xilinx System Generator for DSP in MATLAB are used. The model is compiled and the VHDL code is obtained to emulate it on a Xilinx Artix-7 AC701 FPGA board. Subsequently, the encryption and decryption of digital data is performed using LFSR and BPSK. In addition, the comparison between the results obtained is made, between a DSSS transceiver using a standard LFSR against another DSSS using an extended LFSR. Finally, the design of a graphical user interface is presented, capable of modifying the parameters of the DSSS transceiver model to adapt it to different transmission frequencies.
