This paper aims to present a digital radio broadcasting system that explores the advantages of pseudo-random codes.In this context, a transmitter and its dual receiver are able to reuse frequency spectrum bands without interfering on other existing communication systems.It is proposed a communication system that allows radio broadcasting with the following characteristics: lower transmission power, new communication channels and digital signal processing techinques to add positioning services in two dimensions.
