Philadelphia - Sep 23, 2009 - The first two stages of a project to develop on-channel digital booster technology for FM in-band/on-channel (IBOC) digital radio have now been completed. This work has been undertaken by Ibiquity Digital and is being co-funded by Ibiquity and NAB Fastroad.
On-channel digital booster technology is one of the principal techniques proposed for improving FM IBOC digital radio coverage. The boosters, strategically located within the coverage area of a radio station, would transmit only the digital portion of the hybrid IBOC signal. The approach to digital booster development being undertaken by Ibiquity is aimed at a booster design that is interoperable among the various transmission equipment manufacturers. The technology is reverse-compatible with existing receivers and supportable by existing FM IBOC broadcast products, such as exciters, through upgrading.
A technical report describing the results of laboratory testing of this new digital booster technology is available at the NAB Fastroad website.
