Simulation of the ofdm technique for the transmission of digital radio

Marcelo Herrera Martínez, Miguel Pérez Pereira


The present project is motivated by the necessity of analyzing the technique of OFDM modulation and its performance, focused to the Transmission of Digital Radio. Traditionally all the radio programs are transmitted by FM, and AM modulations, and the radio should be tuned to each one of these frequencies; this used a wide range of the spectrum for a relatively short range of stations, limiting the experience of listening. In this project, a modulation system for Digital Radio Transmission is pretended, in order to combine multiple streams of audio in a relatively narrow frequency band, centered in a defi nite transmission frequency.
