IBOC Technology for Digital Radio

ABSTRACT

Digital television signals are now routinely received over cable and satellite systems, whereas reception of digital radio broadcasts is still fairly uncommon.So let’s see how IBOC system for digital radio delivers CD-quality audio and data services on the existing AM and FM bands.

IBOC stands for In-Band-On-Channel technology and it was developed when the US decided not to adopt the other existing digital technologies in the world. To date, over 100 radio stations in the US have already purchased IBOC transmission systems, and many receivers have been introduced for it.

Digital radio, also called digital audio broadcasting (DAB), is transmission and reception of radio signals in the digital domain, and some of its benefits are as follows: -

1. High-quality audio

2. Wireless data services displayed on radio (artist and song title, traffic and whether alerts and more).

3. Rugged, reliable delivery to fixed, portable and mobile receivers for interference-free reception.

4. Efficient use of the limited radio frequency spectrum available.

5. Easy-to-use receivers.
