Abstract

To show the ease of use of the programming environment of LabVIEW in the teaching of telecommunications at the undergraduate level, it is implemented and simulates a system of modern communications using QAM modulation of higher order and coding Reed-Solomon shortened version (204,188, t = 8), steps used in the transmission of digital terrestrial television DVB-T. The system model is proposed, a brief description of the VI is used and the performance curves of bit error rates are presented in an AWGN channel for each modulation schemes modeled.
