This project presents the history, basic information and advantages of using Software De ned Radio (SDR), diversity, layer division multiplexing (LDM) technique and the latest digital TV standards in a digital communication system. These subjects have been relevant in the scienti c community, making the project attractive in terms of the possibility of discoveries and optimizations. After that, the implementation of a digital communication system using these technologies is proposed. This implementation was performed by means of GRC simulation software and the use of C++ and Python programming languages. Therefore, it was necessary to test the steps of coding, modulation and digital transmission / reception. Finally, tests were performed with systems that use diversity, for example, Single-Input Single-Output (SISO), as well as setting Single-Input Multiple-Output (SIMO), using the settings 1x 2, 1x3 and 1x4, in order to compare possible advantages in spectrum utilization, data rate and system robustness to interference.
