The advent of digital radio broadcasting provides the broadcaster with the opportunity to convey a variety of data types, to considerably enhance a basic audio service. Analogue FM broadcasts already benefit from a variety of features from the Radio Data System (RDS), but while RDS uses an additional carrier to convey this digital data, the emerging all-digital services such as Eureka DAB, Inma...

This paper shows how a PDA (Personal Digital Assstant)can be converted into an audio source within a private network or the web, providing capture, compression and streaming of audio as a real-time mobile service. Once the sound around the PDA has been captured and compressed to mp3 format, the service allows it to be broadcast to a Streaming Server. Once the audio reaches the Streaming Server,...

According to the rapid development of the digital technology, the broadcasting environments are changing into the digital television transmission including the ATSC, ISDB-T, Digital Video Broadcasting – Terrestrial (DVB-T), etc of the high quality and high-efficiency from the existing analog television transmission. In the transition to digital broadcasting, the methods that can efficiently use...

In this paper, we proposed to implement the Digital Audio Broadcasting-(DAB) Transmitter and receiver part. The main problem in frequency modulation is multipath fading and ISI. To solve this problem we proposed the use of DAB with OFDM system. A matlab-simulink model is designed for DAB. The well defined radio equipment designed to broadcast the radio stations provide high-class data and audio...

IBOC DAB (In-Band On-Channel Digital Audio Broadcasting) requires the simultaneous broadcast of an analog and a digital signal within one channel of the FM band. Because broadcasters are adding IBOC to their existing systems, it is vital that they achieve maximum power efficiency while working within their existing space and power limitations. There are currently three different strategies prop...
